Pigmentation markers only — not a general ancestry test.
For each population group, we pool all reference individuals and compute the average allele frequency at each of 71 pigmentation SNPs. Your genotypes are then scored against each group's average frequencies using a log-likelihood under Hardy-Weinberg equilibrium — essentially asking: how probable are your alleles given this group's average? SNPs that vary more between groups (higher Fst) are weighted more heavily. Because pigmentation genetics correlates with geography, results loosely reflect ancestry, but this is not the same as a genome-wide test using hundreds of thousands of SNPs. Show all SNPs
