Why might my ancestry & traits results be different from what I was expecting?

Our ancestry and trait results are statistical predictions based on DNA patterns. These results do not guarantee the occurrence of specific ancestry or traits, which may lead to discrepancies when compared to your personal understanding. These predictions will become more accurate as research includes a wider range of diverse participants. 

It is important to note that ancestry and traits results are different from your health results. The Tier One Population Screen looks for the presence or absence of specific genetic variants with extensive evidence from the medical community that links them to disease risk.
