Most Specific Dna Ethnicity Test – Based on the feedback we’ve received, these 300,000 customers have learned a lot about their family history—the origins of their wisdom and their genetic relatives.
It turns out that AncestryDNA has also learned a lot from our customers. We’ve discovered some interesting statistics on ancestry estimates that can help you learn a little more about your own family history – and we’ll share them with you in this blog post.
Most Specific Dna Ethnicity Test
At AncestryDNA, we estimate a client’s genetic ethnicity as a set of percentages in 26 regions around the world. See the map below for a map of the areas.

We estimate the amount of DNA a client inherits from each of these regions by matching the client’s DNA to DNA samples—from each of these regions—corresponding to documentation. With family trees. For a deeper dive into the science of determining ethnicity, see my previous post on the topic.
Below is an example of an AncestryDNA genealogy estimate. In this post, we’ll explore what AncestryDNA’s ethnicity estimates look like across all of our customers – specifically, how many of these 26 regions are shown in the estimate?
These are the main regions from which you are likely to inherit DNA (the regions, pictured above, that you see when you first look at your ethnicity estimate);
In exploring the overall genetic genetic results of clients selected for scientific research, here are some facts we discovered about the diversity of regions present in client estimates:
At Home Dna Tests Just Aren’t That Reliable
These statistics and averages show the diversity of regions often found in an AncestryDNA client’s ethnicity estimate—and prove that Americans are truly a mix of cultures and influences from around the world.
Advances in DNA science and research are only beginning to have a significant impact on how we understand ourselves and society at large. While DNA testing often confirms what is expected, it can also reveal the completely unexpected. How do your AncestryDNA results compare to our results?
Julie has been a population geneticist at AncestryDNA since May 2013. Before that, Julie received her Ph.D. in Biology and an M.S. in statistics from Stanford University, where he studied genetic data from human populations and developed computer tools to answer questions about population history and evolution. He also spent time collecting and studying DNA using saliva collection tubes like those in the AncestryDNA kit. Julie enjoys spending her time away from the computer in the great outdoors – hiking, biking, running, swimming, camping and picnicking. But if she’s inside, she’s baking and drawing and painting.

Dna Ethnicity: What Do Dna Test Results Mean?
This blog focuses on the technology used behind the scenes by Ancestry. It’s a place to learn about the experiences we have, the challenges we face, and the solutions we use across our engineering and technology teams to create experiences. Consumer DNA testing is becoming more and more popular. More than 15 million people have taken a DNA® test to learn more about their family origins. Despite its growing popularity, many myths persist. Here are 5 myths about taking a DNA® test.
Myth 1: If your sister had a DNA® test, you already know what the results will be. We get 50% of our DNA from each parent, so only identical twins have the same DNA. Therefore, unless you are an identical twin, your DNA® test results may differ from those of your siblings.
Take the results for sisters, Lisa and Francine, who share the same set of biological parents. The DNA test results of sisters Lisa and Francine are different. While Lisa had British traits in her DNA, her sister Francine had no British traits at all.
Myth 2: Like all DNA tests, DNA® requires a blood sample. Fortunately for those who are wary of needles, a DNA® test uses a simple saliva sample to test your DNA. While you may feel a little silly, preparing your sample is relatively quick, with some serious science behind it.

Myth 3: If you know your family history, a DNA® test won’t surprise you. Some people know their family background very well. They have many stories and pictures and may even have extensive family trees that go back centuries. But even family historians may be surprised.
Myth 4: Once you take a DNA® test, you do not retain ownership of your DNA. Many people are surprised that, after taking a DNA® test, you no longer own your data. DNA® does not claim ownership rights in the DNA submitted for testing. You own your DNA. For more information, see the Privacy Center.
Myth 5: A DNA Test® will only reveal your ethnicity. You may have heard stories about people who wondered where their DNA came from. But that’s not all a DNA® test can tell you. It also shows your cousin matches as “DNA Matches,” which are other people who have taken a DNA® test to whom you may be related.
The DNA® test shows you other test takers who may be related to you. You may find that you relate to co-workers like Nika and Krista. Or you might find a long-lost Irish cousin. I have written many times about ancestry results as part of autosomal testing offerings from leading DNA testing companies, but I still have many questions about which ancestry test is best, which is the most accurate. is, etc. Take a look at the “National Percentage – Second Generation Report Card” for a detailed analysis and comparison.
Tips For Making The Most Of Your Ancestry Dna Results
Unreliability means that results are not consistent and often not reproducible across platforms, especially in terms of minority combinations. For example, a German/Hungarian family member shows Native American admixture at a low percentage, around 3%, in some but not all vendors. Their European family history does not reflect Native heritage and, in fact, excludes it. However, their findings suggest that Native Americans shared a common core ancestral population, the Yamanaya, among Asians who settled in parts of Hungary and Germany and also contributed to the Native American population.
Unreliability can also mean that different providers, measuring different parts of your DNA, can attribute the results to different regions. For example, if you take Celtic ancestry, would you be surprised to see the Germanic results and think they are “wrong”? Speaking of the Celts, they weren’t stuck in one area of Europe. And who were the Celts and where did they come from before they became Celts? All this current and ancient combination is carried in your DNA. It is a challenge to touch it and take its meaning.
Unreliability can also mean that tests often do not reveal what is “known” in terms of family history. I put the word “recognition” in quotation marks here, because oral history does not constitute “recognition” and there is no evidence. Most of the time, the documented pedigree is “known,” but you will never “know” about an undocumented adoption, otherwise known as a “non-parental event” or NPE. Yes, this is when one or both parents are not what you think they are based on traditional information. With the advent of DNA testing, NPAs can, in some cases, be detected.
So the end result is that you’re given some very interesting information about your genetic background that often doesn’t correlate with what you expected – and you’re left scratching your head.

However, in some cases, if you’re looking for something specific – like a small amount of American or African ancestry, you can actually confirm it through your DNA – and you can confirm your family history. can One thing is for sure, if you don’t test it, you’ll never know.
By minority admixture, I am referring to the admixture that is several generations back on your tree. This is often revealed in oral history but not proven, and people turn to genetics to prove these stories.
In my case, I have several documented Native American lines and some that are undocumented. All of these findings go too far back, in the 1600s and 1700s, to actually be “found” in autosomal admixture tests. I also have a small amount of African admixture. I know which line it comes from, but I don’t know which grandmother, exactly. I worked systematically with these small percentages and documented the process in a series titled “The Autosomal Self.” It’s not an easy or quick process – and if quick and easy is the type of answer you’re looking for – then doing more, beyond what the testing companies offer, mixing small amounts probably isn’t for you.
Let’s see what you can expect in terms of heritage mix. You receive 50% of your DNA from each parent, and so on, until you eventually get very little (or no) DNA from your ancestors several generations down your tree.
Can You Be 100% Of An Ethnicity On Dna Results?
Let’s put it in perspective. The first US census was taken in 1790, so your ancestors must have been born in 1770, included in the 1790 census, possibly as children, and
