How does AncestryDNA® figure out those percentages in your ethnicity results? By looking at genetic markers in your saliva and comparing sections of your DNA to reference groups from various regions, we can estimate where your DNA most likely originated. This video covers how that process works and more.

Part two of the video highlights the updates and additions to our DNA regions for 2021. Even if you don’t have DNA from a new region, your results could still be more precise than they were before. Watch the video and then check out your latest DNA results.
