DNA testing has become the latest tool for genealogists to research their family history. But have you asked yourself how to interpret your Ancestry DNA test results? This technology claims to give the family historian a link to the past.
Another benefit is that it can connect you with distant cousins. The results you get back though can be quite confusing. So how do you actually interpret these test results?
You’ve taken the next step with your research and now your results are finally ready to be viewed online. You’ve waited for what has seemed to have been an eternity for the results of your DNA testing.
But what does all the data really mean and how can it help you to progress with your family history?
This post will look at the top questions you may have asked yourself about your AncestryDNA test results. But even if you have not taken the next step with your family history research and purchased the Ancestry DNA kit I suggest you to still keep reading.
I want to answer these questions in order to help you with your results, but also to inform you of what you can expect from DNA research.
Questions answered in this post:
- How do I interpret my ethnicity results?
- How do I interpret the map and locations?
- How can I link my DNA results to my family tree?
- What are trace regions?
- Why don’t my DNA results match what I expected?
- Are my results specific to my maternal and paternal lines?
- How accurate are the results that I get back from this test?
- What is a low confidence region?
- What does confidence percentage mean?
- What about the indigenous ethnicity that’s returned in my results?
How Do I Interpret My Ethnicity Results?
One of the key results that you get back from AncestryDNA is an estimate of your ethnicity. The keyword here is obviously “estimate“, where your DNA is compared to genetic profiles that have been gathered from a reference panel.
The people that make up the reference panel have been chosen as they have deep-rooted ancestry within a particular region. In all, Ancestry DNA covers 150 regions all around the world, (updated from 26 regions).
Your DNA is compared to each of these different regions and so the results, given as percentages, that you get back from the testing can tell you where your ancestors likely came from.
How do you interpret your ethnicity results?
Now that you understand about how your ethnicity is calculated I will explain how you can interpret the results of this testing.
The results of your ethnicity testing is displayed to you in the form of a color coded pie chart. Here the chart is divided into wedges which are given percentages as to the likelihood of where your ancestors originated.
So it may show you that you have a score of 99% ethnicity originating from Europe. This can be broken down even further to include areas such as Great Britain, Ireland, or even Scandinavia.
To help you interpret these results there is also a map showing you these locations which are color coordinated based on the results of the pie chart. This map is also interactive!
So you can click around the map, zoom in and gather even more details. Zooming in will then show you areas of varying degrees of shading. The darker the shading then the higher the chance that your ancestor originated from that area.
This is a great tool to help you show you where next that you can look for further information.
See all 150+ regions
If you click on the See all 150+ regions link you will then see all of the ethnicity regions. And you will also see them marked on the map.
The numbers that appear to the right of each of these regions refer to Genetic Communities. These numbers will be the same for everybody and are NOT specific to you. They are merely a link to groups that can help you further with your research.
From this section you will see the same color-coded dots for the regions that you have been identified with. Any region that you are not identified with will be colored with a grey dot.
For further information please check out Genealogical Musings – AncestryDNA’s New Arrangement of Ethnicity and Genetic Communities.
How Do I Interpret the Map and Locations?
The second advantage of AncestryDNA is the possibility of matching you with other Ancestry members that have taken the test. If both you and your match have created an online family tree then you have access to a ‘Map and Locations‘ map.
This is another great tool that will help you join the dots within your family history research. This map may display to you different colored pins of where your ancestors were born, the same for your DNA match and also any overlapping birth locations in both family trees.
These pins may contain more than one person for each location. There is also a legend at the bottom of the map to help you decipher what all the different color coding means.
How Can I Link My DNA Results To My Family Tree?
Ancestry DNA will compare your DNA test results with other Ancestry members. To further improve your matches Ancestry will compare the people contained within your family tree and the people in your match’s tree. With that in mind then it is a good idea for you to link your DNA test results to your family tree.
You can do this by accessing your personal status page and going to Settings. Then scroll down and select the ‘Family Tree Linking‘ option. Here you will be able to link to your DNA results to your tree.
Please note: At present you can only link your DNA results to one family tree that you have created on Ancestry.com.
What Are Trace Regions?
The regions that your ancestors are likely to have come from are given as percentages as I have explained in the first question. If any of the regions return a value between 0 and 15% then these are known as ‘trace regions‘.
As these percentages are quite low and these are estimates it may be that you actually do not have ancestors from these regions at all. However, in time as more genetic signatures are concerned these percentages for your trace regions may improve to give you more accurate results.
So it is well worth checking these values occasionally for updates.
Why Don’t My DNA Results Match To What I Expected?
This is a very common question asked by many people who have taken the AncestryDNA test. It can also be the most frustrating aspect of the test, when your results are totally different to what you thought your tests should have shown.
DNA testing technology has come along way since it began about twenty years ago. But it still has a long way to go before it can be claimed as perfect. As Ancestry’s ethnicity algorithm and prediction models take time to improve there are three reasons why there will be unexpected results.
The 3 reasons why you will get unexpected results with your DNA results:
- Your genetic ethnicity results goes back further how far you have traced your family tree.
- If your ancestors came from a certain area they may still have genetic influences from other places.
- Your DNA doesn’t match closely with your ancestors.
Are My Results Specific To My Maternal and Paternal Lines?
Ancestry offers you Autosomal DNA testing that looks at over 700,000 markers that you have inherited from both your parents. However, this type of testing does not isolate the heritage of your maternal or paternal line. So you cannot find out as such where your maternal ancestors originated came from, only where ‘your‘ ancestors came from.
How Accurate Are The Results That I Get Back From This Test?
Ancestry DNA tests your DNA using advanced scientific techniques and looks at over 700,000 markers in your sample. These markers look at differences between your DNA and that within Ancestry’s sample.
However, if your DNA is not of high quality then you will need to supply a new sample. With that said it is a good idea to be careful when providing your saliva sample.
The database of DNA samples that Ancestry contains continues to grow. And over time you will get more accurate results. You will get updates from Ancestry as new information is collected.
What Is A Low Confidence Region?
Below your major ethnicity results you may see some regions that are highlighted as low confidence. Typically these are regions with less than 4.5%, but they can go as high as 6%.
It is difficult to say whether these particular regions, (or the other regions that you have been matched with), are truly accurate. They are after all an indication of confidence that you have some connection to a particular region.
These results show that you do have a little bit of DNA from these regions and so these low confidence regions should not be disregarded.
If you do have low confidence regions in your results then you should ask yourself the following questions:
- Do these low confidence regions match what information that you already know?
- Are these low confidence regions a surprise to you?
- Are these low confidence regions in an area nearby where you know that your ancestors originated from?
Finding out more about these regions may actually help you build out further branches of your family tree. And also it may help you discover ancestors that you never knew existed.
What you can do next:
- Get your relatives tested – To help get more information about your ancestors you could actually ask your relatives to purchase an AncestryDNA test. This will provide you with more results that you can use for your research.
- Upload your DNA results to GEDmatch – The GEDmatch website is a free service that you can use. Just upload your raw DNA data to the site and you will get more results for you to work with.
- Contact your DNA matches – Why not contact the people that you have been matched up with on Ancestry. Ask them if they have similar results with respect to low confidence regions.
What Does Confidence Percentage Mean?
The confidence that you are matched with someone is given as a percentage. This value will help you to concentrate on the matches that matter. So with a higher value the more chance that another Ancestry member who has taken the test is related to you.
There are over 700,00 markers in your DNA that are tested and compared to other Ancestry members. The number of matching strands will determine how closely you are related to another Ancestry member.
As Ancestry tests different populations the higher their confidence level will become.
What About The Indigenous Ethnicity That’s Returned In My Results?
If you live within the United States then AncestryDNA may provide you with feedback as to whether you have Native American heritage. The testing may also show that you have indigenous ancestry within maybe Canada or Mexico. However, there is no way to determine which tribe that your ancestors belonged to.
My Final Thoughts On How To Interpret Your Ancestry DNA Results!
DNA testing is a great tool for any genealogist who wants to further their family history research. But the results that you get back can be somewhat confusing. I therefore hope that I have answered any questions that have bothered you with this type of testing.
If not then please feel free to contact me or comment below!
A DNA test can help you to further your research. So if you have hit a brick wall and want to move on then a test can help you to move on.
Your results can show you where your ancestors originated from and so where you can look next for documents, records and any other type of material. So if you discover that your ancestors came from a certain country then you can explore Ancestry’s database of records for that respected country.
Also, with this type of testing you may connect with other Ancestry members as I have discussed in this post. A great advantage of this is the sharing of information that your match possesses.
You can share with your match information regarding your side of the family and vice versa. Information that can be shared could be photos, documents, letters and whatever else and whatever else you can think of to share.
So you can further your family tree in this regard. If you have not tried AncestryDNA testing yet then I do recommend that you take the next step to help further your genealogy research.
