"Basically, races have allele frequencies that are similar and some that are different. This is why, even if someone is 100% ancestrally Scandanavian, they may register as 0.1% Vietnamese.
That's because they happen to have some allele frequencies that are more common among Vietnamese than Norwegians.
Like, on most of the genome, Africans and Europeans don't differ very much in allele frequency. Ancestry is a probabilistic estimate."
