Ethnicity Estimate 2020 White Paper

The AncestryDNA® science team has developed a fast, sophisticated, and accurate method for estimating the historical origins of customers’ DNA going back several hundred to over 1,000 years. Our newest approach improves upon our previous version in the number of possible regions that a customer might be assigned (from 61 to 70) as well as an increase in accuracy to both regions assigned and the percentage assigned to each region. We have added nine new regions as well as made improvements to the composition of our reference panel and inference algorithm, resulting in more accurate estimates overall. Given the cutting-edge nature of this type of science, we will continue to refine our approach and improve estimates.
