FamilyTreeDNA Review
| #2 |  |
FamilyTreeDNA (FTDNA) is the best DNA ancestry test if you’re committed to serious genealogy research. This company is the only service that offers all three types of tests separately: autosomal, Y-DNA and mtDNA testing. Their Y-DNA and mtDNA tests are much more in-depth than other companies’ maternal and paternal-line analysis. (Learn more about these different tests.)
Also, FTDNA is one of few services that offers a chromosomal browser, which allows you to compare your matching DNA segments (blocks) with each genetic match. You get the email addresses of your matches and can join targeted genealogical projects within their network. This is one of a few services that gives you the ability to transfer your data from other services to help you further your research.
You may have heard about FTDNA’s recent agreement to work with law enforcement to upload genetic files to help identify a perpetrator of a homicide, abduction or sexual assault, or ID the remains of a deceased individual. If this causes privacy concerns for you, FTDNA allows you to opt out of Law Enforcement Matching, so your DNA results on file will not be included in their searches.
Best For Advanced Genealogical Research
FTDNA gives you a list of all your genetic matches who share common ancestors from your maternal and paternal lines from the past 5 or so generations. You can even view, sort and compare individual DNA matches by parental lines and contact matches via email (if they’ve permitted access). Their separate mtDNA and Y-DNA tests give you uniquely specific analysis into your DNA, and their online resources are phenomenal.

23andMe Review
| #3 |  |
23andMe is your best bet if you want to trace your lineage and get disease-risk and carrier-status DNA results. They offer two testing kit types — an autosomal Ancestry test for $99 or a Health + Ancestry test for $199.
On the ancestry side, you’ll get reports on your ethnic composition, haplogroups and Neanderthal ancestry. 23andMe also provides you an anonymous report of where your current genetic matches live in the world, and you can opt-in to their DNA Relatives tool to find, connect and message those who share DNA with you. If you want to use your DNA results to help you trace your family tree, however, 23andMe’s research tools and genealogy community aren’t up to par with FamilyTreeDNA or Ancestry.com.
23andMe is the only direct-to-consumer genetic test that has FDA approval for 10+ genetic health risks, including late-onset Alzheimer’s, Parkinson’s, Hereditary Thrombophilia and most recently Type 2 Diabetes and three genetic variants found on the BRCA1 and BRCA2 genes known to be associated with a higher risk for breast, ovarian and prostate cancer.
Other health results include 40+ FDA-approved carrier status reports (whether you carry genes for certain health conditions), 5 wellness reports (lactose intolerance, for example) and 25 trait reports (male bald spot, unibrow, etc.).
Best For General Ancestry & Disease Risk Screening
If you want to learn where your ancestors lived around the world and, at the same time, gain insights into your health and risk for certain diseases, 23andMe’s Ancestry + Health test is the way to go.

African Ancestry Review
African Ancestry was launched in 2003, and since that time, it has partnered with historians, archaeologists, anthropologists and other geneticists to build the largest collection of African lineages in the world, including over 30,000 indigenous African DNA profiles.
This company offers separate mtDNA and Y-DNA tests but no autosomal test. African Ancestry says they can trace your roots back to a specific present-day African country, but that’s a somewhat problematic claim. Given the science they use and the limits of DNA ancestry testing in general, what they can do is determine a likely estimate of broad genetic matches “based on the frequency of identical and closely related haplotypes,” according to their website. They also provide broad results from other continents.
Best DNA Test To Discover Ancient African Roots
Do you want to know which specific area, or perhaps even tribe, in Africa your ancestors hailed from? If you know (or highly suspect) that you are of African descent, African Ancestry traces your African roots from 500 – 2,000 years ago.

GPS Origins By HomeDNA Review
GPS Origins test by HomeDNA uses a unique ancestral tracking technique that breaks down your gene pool and family migration patterns. Their in-house and highly-accredited laboratory, DNA Diagnostics Center (DDC), tests 800,000 autosomal genetic markers and analyzes 1,000+ reference populations and 40+ gene pools to tell you where your ancestors moved over hundreds of years starting roughly 1,000 years ago.
Although their GPS Origins test kit is expensive, HomeDNA allows you to upload your results from 23andMe, Ancestry.com, the FamilyTreeDNA Family Finder or National Geographic Geno 2.0 for HomeDNA’s unique analysis for a $39 fee. HomeDNA also provides special editions of their GPS Origins test.
- The African Edition autosomal test analyzes 11 African–specific gene pools and ancestry markers from more than 100 African populations. You receive your African ethnicity in percentages and can see your ancestors’ migration routes going as far back as 2,000 years, along with anthropological stories explaining the movement of your DNA over time.
- The Asian Edition test analyzes 17 Asian gene pools and goes back 2,000 years, with date stamps and geographic coordinates.
Best For Early Migratory Patterns
Want to know where your early ancestors originated from and migrated to over hundreds of years? The GPS Origins tests give you basic migratory patterns within certain areas of the globe starting as early as 2,000 years ago based on your genetically-matched haplogroups.

Living DNA Review
England-based Living DNA launched in early 2015. At the time, they claimed to be the “first truly global DNA test” because they broke down ancestral origins across 80 worldwide regions. AncestryDNA and 23andMe, however, have put that claim to rest as both sites have seriously improved their regional ethnicity analysis. Living DNA does still have the edge on British ancestry — they break down your roots across 21 specific regions in the British Isles.
If you already have a good idea that your roots are from the United Kingdom, Living DNA could be a great test for you to delve deeper into the region. Living DNA has partnered with several leading genomics, analytical, testing and research organizations, which lends them a lot of credibility in our book. We’re keeping our eye on this relative newcomer to see how their reputation develops.
Best For British Heritage
If you have Brit in your blood, Living DNA is your best choice for DNA testing. Based in the UK, their database is specifically geared toward the European and UK populations, making their results more comprehensive in those regions.

MyHeritage DNA Review
MyHeritage is one of the most popular genealogy research and family tree websites in the world. In September 2016, they launched an autosomal DNA ancestry test at a competitive price. This DNA heritage test is similar to AncestryDNA, with fewer ethnic regions identified.
Although the test is relatively new compared to the top 3 services, their database has grown to 1.4+ million people, and they use FTDNA’s highly-accredited testing lab. An advantage of MyHeritage DNA? You can import DNA testing results from competing companies to compare with their database for free. Most other services (except FTDNA) either don’t give you this option or charge you a fee.
Best For Enhancing Your Online Family Tree
With more than 3.3 billion people in family trees and 103+ billion users worldwide, MyHeritage’s Family Tree Builder and related services are among the best online. How do you benefit from connecting your DNA to your family tree? DNA results can prove or disprove documented family tree connections. Family trees are also vital for understanding the relationship path to DNA matches.

National Geographic Geno 2.0 Review
Geno 2.0 DNA Ancestry kits are no longer available for purchase since the public participation phase of the National Geographic Genographic project ended in late May 2019. According to their website, if you already purchased a kit, you may still send it in for processing “in accordance with the Terms and Conditions of sale.” They also say that customers will still be able to access their test results online until the end of 2020.
Vitagene Health+Ancestry Review
Vitagene Health + Ancestry by HomeDNA is a combined autosomal DNA test that analyzes your ethnic ancestry and several health traits from one single cheek swab. Its approach is similar to AncestryDNA’s test but with noticeable limitations.
There isn’t much to get excited about with Vitagene’s test. Their ancestry analysis only gives you ethnicity results for 25 regions around the world with percentage breakdowns — you can get these results and more (e.g., familial matches) from AncestryDNA, 23andMe and other ancestry tests.
Vigagene also looks at specific genes related to vitamin deficiencies and common sensitivities, like gluten or lactose intolerance, as well as several other physical and wellness traits (AncestryDNA’s test now does this, too). Finally, there’s an online questionnaire, where you provide secure and confidential information about your medical history and lifestyle.
They claim they can then use the results of their DNA test and your medical history to develop a personalized plan for exercise, diet and supplement recommendations. But here’s where there’s a problem — they take the results too far. No published scientific studies show that genetic tests can give you useful and actionable information about boosting your wellness through diet and exercise solely based on your genetic profile.

Other Types Of At-Home DNA Tests
DNA Paternity Test
Historically one of the more common types of DNA tests, a paternity test determines the biological link between a father and child. There’s even a non-invasive prenatal paternity test available now. Read our Paternity Test Comparison for the scoop.
DNA Health Testing
At-home DNA testing for most medical and health-related purposes is still in its infancy, but scientists are making advances every day. It’s always a good idea to talk with your physician and/or a genetic counselor before deciding whether to test yourself. A counselor can also help you decipher the results.
Check out our article on DNA Testing For Health Reasons to see which at-home tests are legit.
Note: Keep in mind, these tests analyze your genetic makeup to see if you’ve inherited genes that could make you more likely to develop a certain condition. But they can’t predict whether you’ll actually get that disease (or even your chances of getting it).
Genetic Testing For Cancer Risk
Some people have a higher risk of developing specific types of cancers that tend to run in the family. In these cases, a physician may test your DNA to look for gene mutations that could indicate a higher risk. One of the better-known examples is testing for mutations in the BRCA1 and BRCA2 genes (breast cancer genes) in women whose mother and sister have had breast cancer.
Genetic Testing For Carrier Status
Want to start a family, but you’re worried you may pass on an unwanted risk to your child? Some DNA tests can tell you if you’re a carrier for certain inherited conditions, such as cystic fibrosis, sickle cell anemia or hereditary hearing loss. A positive match doesn’t mean your child will inherit the condition; it just lets you know whether you carry the gene.
Not all DNA tests are the same. A carrier status DNA test, for example, focuses on the specific markers known to be associated with certain inherited conditions. On the other hand, DNA genealogy tests focus on specific markers related to our ancestry.
Pet DNA Testing
Why should your pets be left out of the family tree fun? You can now test dog DNA with Embark, a top-rated company that can help you find your dog’s breed makeup and identify many health markers. Your cat can get in on the genealogical action too, with the reputable cat DNA company, Basepaws.
Statistics & Facts About DNA Tests
Here are some recent stats and fun facts related to DNA and its growing popularity.
- As of early 2019, more than 26 million consumers have taken DNA tests with commercial DNA kits.1
- More people took DNA tests in 2018 than all previous years combined. 1
- If DNA test trends continue, there could be 100 million people’s genetic info in commercial databases by 2021.1
- Privacy is the #1 concern people have about DNA tests. 2
- 40% of surveyed travelers reported that they want to take, or have taken, a trip inspired by their DNA test results. 3
- A California-based travel agency Authentic Vacations booked $1.5 million in Ancestry tours in 2018 (nearly double compared to 2017).3
- Music sharing service Spotify has teamed up with Ancestry to provide musical DNA playlists inspired by your test results. Since launching in September 2018, more than 10,000 people have signed up for a custom playlist.4
- According to Google Trends, West Virginia, Maryland, Massachusetts and Vermont are the states most interested in DNA kits in the past 5 years (since April 2014). 5
How Does At-Home DNA Testing Work?
Step 1: Order Your Kit
Order your kit online from anywhere in the world. It takes about a week to receive the kit. The package should arrive sealed, so you are certain it has not been tampered with.
Step 2: Set Up Your Online Profile
You’ll need to activate your kit online using a unique code provided to you. This connects your name and contact details to your sample so you can track progress as it’s tested and later view results. You’ll most likely sign a consent form and agree to the company’s legal terms and conditions before getting started.
Step 3: Provide A DNA Sample
Now for the fun part — providing your DNA sample! Most tests offer cheek swab tests. AncestryDNA, 23andMe and NatGeo Geno 2.0 tests require you to spit in a vial.
Either way, they recommend not eating, drinking, smoking, chewing gum or teeth brushing at least one hour before to ensure a good sample. Also, wash your hands before opening the test tubes to ensure a clean sample.
Step 4: Seal & Ship Your Sample
Once your samples are complete and ready to go, seal the samples in the specimen bag, place them in the provided mailing envelope and drop it in your mailbox for delivery. Don’t forget to make sure your unique ID is on each sample, so the labs have a way to track it back to your profile.
Step 5: Wait For Analysis
In an age where we can get most things instantly, you might be anxious to get results right away. But, how long does a DNA test take to come back? Given the complexity of the process of analyzing your DNA and comparing your results to other samples, expect to wait anywhere from 4-10 weeks depending on the company.
Step 6: View & Share Your Results
To access your results, sign in to the online portal using the login you created when you activated your kit (results will not be mailed to you for privacy reasons). Once logged in, you can view and analyze your DNA in more detail using the provided percentages, maps and more depending on which kit you chose.
Types Of DNA Tests For Ancestry: Autosomal, mtDNA & Y-DNA
Now that you have a better understanding of the scientific part let’s define the various types of tests, what to look for and who can take each one. It’s important to do your research about the kind of test to make sure you’re testing your DNA for the specific information you’re looking for.
Autosomal DNA Test
Autosomal DNA tests look at chromosomes 1-22 that you’ve inherited from both your parents. Don’t know much about your grandparents or other relatives? Autosomal DNA testing can determine how closely related you are to other individuals.
- Who Can Take The Test: Males and females.
- What It Tests For: Autosomal DNA testing matches you with other individuals based on a certain amount of shared DNA.
- What It Can Reveal: You can expect to find matches as far out as 5th cousins and in some cases even further. Tests analyze shared DNA and give you your matches as well as how much DNA you have in common. Autosomal tests also give you estimates of your ethnic origins from around the world.
- How Far Back Are Results: Autosomal DNA tests trace back anywhere from 5 to 10 generations on both your mother’s and father’s sides of the family.
What Are Ethnicity Estimates?
Autosomal DNA tests match your DNA with population samples and studies from across the globe. When you get your DNA test results back, you’ll get a report that gives you a mixture of percentages (ethnicity estimates). These are your unique percentages of where your ancestors lived in defined geographical regions, i.e., 82% British Isles, 10% Eastern European, 2% Native American and so on.
Note: Each company’s ethnicity report differs by their defined global regions, how they present their data to you and the number of population studies they use in their analysis. Your percentages can also differ because of each lab’s unique testing methods. Some autosomal tests also look at parts of your DNA going back even further.
mtDNA Test
A mitochondrial (mtDNA) test traces your mother-line ancestry using the DNA in your mitochondria. mtDNA is passed down unchanged by every mother to all her children, both male and female.
- Who Can Take The Test: Males and females.
- What It Tests For: mtDNA tests along the direct maternal line, examining genetic markers on your mtDNA, which is passed down from mother to child each generation.
- What It Can Reveal: Your direct maternal deep ancestry and which haplogroup you belong to.
- How Far Back Are Results: All humans descended from Mitochondrial Eve, who lived an estimated 200,000 years ago in Africa. Her descendants are organized into different branches called haplogroups.
Y-DNA Test
The Y-chromosome DNA (Y-DNA) test traces direct male-line ancestry — grandfather to father to son and so on. The Y-chromosome passes down each generation virtually unchanged. Since females don’t carry the Y-chromosome, they can’t take this test. Females, however, can learn something from this test by having a brother, father, paternal grandfather, paternal uncle or a male cousin (your father’s brother’s son) take a test for you.
- Who Can Take The Test: Males only (because women don’t have a Y-chromosome).
- What It Tests For: The Y-DNA test traces direct male-line ancestry. Each male’s Y-DNA test results are compared to other males’ results to find out their most recent common ancestor (MRCA) in their direct patrilineal lines.
- What It Can Reveal: This test can tell you which Y-haplogroup you belong to if you’re male. Your Y-DNA haplogroup reflects the ancient ancestry of your paternal line.
- How Far Back Are Results: Like mtDNA tests, Y-DNA tests can go back hundreds of thousands of years.
Other Terminology & FAQs
What Is DNA?
DNA stands for “deoxyribonucleic acid,” and everyone’s DNA is unique to the individual. More than 99% of your DNA is the same as everyone else’s in the world. But there are small groups of sections across each person’s genome that differ (these variations make you the unique person you are).
What Is A DNA Test?
DNA analysis looks at small sections of DNA, called “markers,” to create your DNA profile — a unique genetic fingerprint. Not every DNA test, however, is the same, and not every test’s design finds the same information from your DNA.
What Are Genetic Markers?
A genetic marker is a DNA sequence with a known location on a chromosome. Scientists use genetic markers to identify cells, individuals, populations, etc.
What Does Autosomal Mean?
Autosomal refers to a chromosome that is not a sex chromosome. People have 22 pairs of autosomes in each cell, as well as 2 sex chromosomes (X & Y in a male and X & X in a female).
What Is Shared DNA?
Two people who share identical segments of DNA share a recent common ancestor. The relationship between relatives (siblings, cousins, etc.) depends on the length and number of these identical segments.
What Is Deep Ancestry?
Deep ancestry is based on either mitochondrial (maternal) DNA or Y-chromosome (paternal) DNA, and it shows a single line of descent. It’s often referred to as a direct maternal line or direct paternal line, going back hundreds to thousands of years.
What Does Haplogroup Mean?
A haplogroup is a genetic population (group of people) who share a common ancestor on the direct paternal or maternal line.
What Is Y-Haplogroup, E3a, Q3, Etc.?
Each haplogroup is assigned its own group “name,” which consists of a letter of the alphabet followed by more specific refinements indicated by additional number and letter combinations. Some haplogroups indicate clear ethnic groups. For example, the Y-haplogroup E3a is the most common among African Americans, and Y-haplogroup Q3 solely includes Native American populations.
How Accurate Is DNA Testing For Ancestry?
DNA testing for forensic purposes, paternity and ancestry are 99.9% accurate. This DNA accuracy level for ancestry pertains to matching relatives, not for ethnicity results.
What About DNA Testing Privacy?
Are my DNA sample and results protected? We see this question often. What do companies do with your results and private information? The best testing sites don’t share your DNA results with insurance companies or other third parties. We recommend you read each company’s privacy policy before ordering a test if you’re concerned about your results ending up in the wrong hands.
In 2008, the U.S. passed the Genetic Information and Non-Discrimination Act to protect citizens from having their genetic information used against them for health insurance or employment purposes.
Do My Parents Or Siblings Need To Take A DNA Test For My Results To Be Accurate?
It depends on what type of information you’re looking for. It’s not necessary if you just want general ethnicity results. An autosomal DNA test will tell you what’s been passed down through your mother and/or father’s blood line, so save yourself the money!
But keep in mind, each person inherits different percentages of each parent’s DNA, and every person is different (even twins!). So, if you want the most complete results, everyone in the family should test.
Why Did My Sibling (& Even My Twin) Get Different Results From Mine?
Every person gets half of their DNA from their mother and half from their father. But what ends up in each half differs for each sibling. For example, you could’ve inherited more of your mother’s Asian DNA, and your brother got more of your mother’s European DNA. The same goes for the DNA you inherit from your father.
Can DNA Tests Tell Me What Countries My Ancestors Lived In?
In most cases no, although some (like AncestryDNA and 23andMe) will break them down to very specific regions. Be wary of these specific breakdowns because they’re typically based on very small population samples, so the results aren’t representative of a large enough population sample to make them highly valid (see below for more detailed info).
How Accurate Are DNA Ethnicity Tests?
DNA ethnicity results are the least reliable part of DNA tests, but the science behind this testing is improving. AncestryDNA and 23andMe have recently dramatically expanded the number of global regions they identify in your ethnic mix, but drilling down to specific countries is complicated and problematic. Why? There are two major reasons:
- Each company that offers ethnicity tests uses groups of reference populations to compare your results and place you in an ethnic group. Results, however, can vary widely based on which and how many of these reference populations a certain company uses.
- Over the course of hundreds and thousands of years, there has been a great deal of intermixing of populations, particularly in Europe. Let’s use warfare as a good example. Wars cause invasions, which in turn change country borders and cause the mixing of disparate populations. Refugees migrated to different parts of their continent, further mixing people of different ethnic regions.
Because of these factors, you can see why your ethnicity results are just estimates. The better testing companies, however, give you confidence levels for each of your ethnic percentage results, so you get a better idea of how “accurate” your results are.
How Accurate Is DNA Testing For Health Reasons?
The lines are a bit more blurry when it comes to DNA testing for disease risk (i.e., health).
The Centers for Disease Control and Prevention and other federal organizations want the public to be aware that many companies are prematurely marketing genetic tests for disease risk with limited scientific backing. Many of these tests may not provide valid or useful results. Why? Researchers have yet to identify a large part of the genetic makeup with most diseases.
23andMe, however, is one company that has received FDA approval for a few of its health-related DNA tests. You can discover your genetic disease risk for certain cancers, Parkinson’s Disease, Late-Onset Alzheimer’s Disease, Celiac Disease and other hereditary conditions. Learn more in our article about 23andMe and other DNA tests for health reasons.

I have a problem and am very upset about the DNA test I have taken from AncestryDNA:
Example 1: It shows that I am 48% from Caucasia, but there are 50 Ethnic Groups in Caucasia: Armenians are completely different than Georgians, which one I am from?
Example 2: It shows that I am 36% from Persia, but Persia also included in Caucasia, and it also has many different Ethnic Groups.
Example 3: This is also very interesting to me: Although it is not shown that I have any connection with Greece, 98% of my 4th Cousins are Greeks…:)
I am willing to take another test, of course with another company, if you could advise me one, please. I really, really have to know who I am…:)
Thank you for your time and efforts,
Hazel
I have already done 23andMe. I like it a lot and I am learning more every time I explore results or my 1000+ living DNA relatives. My one issue is that it combines all UK and Irish descent into one statistic. I would like to find out my percentage breakdowns of Irish, Scottish, and English heritage. Is there another site that identifies these more specifically?
LivingDNA has the most thorough breakdown of the British Isles. AncestryDNA has a good breakdown in England, but they lump Ireland, Scotland and Wales together in one region. Hope this helps!
Thank you for all the information, but it’s all a bit overwhelming. I have a written family tree, for the most part, and some previous ancestors researched some members of my family all the way back to the 1100’s. But there are still a lot of gaps. I’m not that interested in finding family members, but I AM interested in finding where in Europe most of my ancestors came from (I know I am Dutch and German, but what else?) There is also a bit question if my father’s family has Native American in it; according to family “legend”, we are Choctaw and Comanche. I realize these DNA test kits can’t break down individual tribes, but which kit would be the best for 1) finding out exactly where all in Europe all my ancestors come from, and; 2) am I part Native American? thank you so much!
I’d recommend going with the AncestryDNA test. They can give you a better breakdown in Europe as well as Native American results. Good luck!
I have been raising my grand daughter basically her entire life. She will be 18 this year. Her mother has left her with me. I told her she loves you so much she knew you would be safer with me.
Her mother will not give us any information about her father or does not know. Her mom has married twice, divorced twice, has a 1/2 brother, and now has taken off again to another state to live with another man.
Which of the services would be the best one to use? Considering, we not only want her heritage and medical information, we also hopefully someday will meet the rest of her family.
This will be my birthday gift to her this year. I can???t imagine any better gift this kid deserves. No one should feel unwanted.
Thanks,

We are adding several new DNA testing companies to our reviews, including Africanancestry.com. Stay tuned!
You are correct! Scientists have made a lot of progress in sequencing the human genome through the Human Genome Project and other research over the last decade. What they???ve discovered makes DNA testing more accurate than ever before ??? and more discoveries are made every day!
In the future I want to test myself and my husband. Should we plan to test the same way? FTDNA Y-DNA and MT-DNA for my husband and just MT-DNA for me?
I would like to feel confident before ordering all these very expensive tests.
Thank you, Monica
Whether you decide on the Y-DNA and Mt-DNA tests really depends on how in-depth you want your research. These tests can help you locate potential sub-groups of relatives and ancestors. If you just want more general heritage information, then you only need to do the Autosomal test for each person. In either case, you definitely want to do the Autosomal (Family Finder) test for each person you mention. Good luck!
I’d recommend AncestryDNA because they have the largest DNA database so you’re more likely to find living relatives and potential family trees that can help you trace their heritage. Good luck!
I have hit two brick walls in my family research. My paternal wall stops at the second generation. My maternal wall stops at the third generation. What DNA test do you believe might be beneficial to my efforts?
Thank you for your time.
Hi Margaret,
Can you tell me more about what you mean by hitting a brick wall? Do you mean in terms of genealogical research into your family? Can you give me more information about what you know in terms of ethnicity in your family?
I have traced my maternal side of ???the tree??? over 30 generations. However, I am stuck at three generations of my paternal “Jones” side of the tree. Might you offer your opinion as to the best DNA program to follow?
Respectfully yours.
Hi George, I’d recommend Family Tree DNA or Ancestry for your “Jones” side of the family. This surname is largely found in the British Isles, and these two companies can help give you some genetic matches on that side of your family.
With all that possible mixture, what would be the best testing company? And would having my son also tested be helpful?
I’d suggest you and your son both test with either Family Tree DNA‘s Family Finder Test or AncestryDNA. Either will help you get some answers that you’re looking for. Good luck!
I did the Ancestry dna test and was highly disappointed and frustrated. My paternal grandfather was 100% Cherokee and not a single drop of Indian showed up in my test. I contacted Ancestry about it and they said that even though I have it in me, it doesn’t always show up on the test. They tried explaining it to me in a way of if your dad has green eyes that doesn’t mean your eyes will be green. Which doesn’t really make sense to me. DNA is DNA, so I don’t get why it doesn’t show up. I kind of said to my mom in a half joking way that if she had an “affair with the milkman”, now would be the time to tell me. Of course nothing like that is really true, but it makes me wonder…..I have also been in contact with a cousin on my dad’s said, and she said her daughter took the same test and got the same results I did. My grandfather is listed on the Dawes rolls also. I don’t know if you have an explanation for me. I feel like I was conned out of money for a test that obviously not 100% accurate. But I was wondering if I did another company’s test, would I get the same results? I wanted to try the 23andme for the health aspect of it too. Any advice?
thank-you for all of the information. there is a lot to choose from. From what I know I have both English/Scottish and Eastern European/Ukrainian in me. My husband swears he is of Viking Blood and has English/Scottish in him. Any thoughts on what would be the best tests? Thank-you.
