Continental groups showing the largest degree of genetic differentiation. For each FDR-SNP, we determined the allele frequency difference between populations in each continental group (Africa, Eurasia, East-Asia and America) and the rest of the world, and we assigned it to the continental group that showed the highest frequency difference. The histogram reports the number of FDR-SNPs in HDIs assigned to each group.
