AncestryDNA uses two different approaches to figure out the regions in your DNA Story. In one we compare your DNA to the DNA from people in a reference panel. (The second uses Genetic Communities. Read more about communities.)
Using a Reference Panel
2020欧洲杯在线网址A reference panel is made up of people with a long family history in one place or as part of one group. To make it into the AncestryDNA reference panel, these folks need two things. First, they need a paper trail that proves their family history. Then, they must have their ethnicity confirmed at the DNA level. It is not easy to make it into the panel!
To tell your DNA story, we compare your DNA to the people in the reference panel and look for DNA you share. If some of your DNA is similar to the DNA of folks from Senegal, for example, we assign that part of your DNA to our Senegal region. And so on until we have looked at your whole DNA sample.

Building a Reference Panel
The current AncestryDNA reference panel has 40,016 DNA samples that divide the world into 61 overlapping regions and groups.
Here is the breakdown of how many individuals are in each of the 61 regions:
|Region||Number of Samples|
|Aboriginal & Torres Strait Islander||14||Baltics||147|
|Benin & Togo||287|
|Cameroon, Congo & Southern Bantu Peoples||535|
