How can I confirm the significance of a low percentage of admixture, such as 4% Native American or 3% African?
There are two ways for you to confirm the value of this estimate: You may have access to historical records or other provenance that leads you to confirm or refute the admixture. For example, if your records suggest that you have a grandparent of East Asian heritage and you register with the test as of 5% East Asian, the two observations combined make a stronger case for East Asian ancestry than either on their own.

Lets say you register with 4% African and you want to know whether this 4% is in error or is accurate. You obtain the admixture proportions from your parents and each is 100% European. Chances are the 4% was a result of statistical noise. However, if your mother was 15% African and your father was 100% European, your non-zero percentage of African is likely to be an accurate indicator of African ancestry. • I think I have American Indian heritage, but my test results show that I am 100% European. • Barr

You obtain the admixture proportions from your parents and each is 100% IndoEuropean. Chances are the 4% was a result of genotyping error. However, if your mother was 15% African and your father was 100% IndoEuropean, your non-zero percentage of African is likely to be an accurate indicator of African ancestry. This is similar to option A), where you are relying on two different sources of information to help you hone in on the most accurate answer possible. Virtually e
