Standard deviations of call rates represent the variance among individuals within the groups, and standard deviations of the heterozygosity values represent the variance among the 11,555 SNPs. Values are calculated for each ethnic group and *for the entire set of 307 individuals aggregated as one common group. Heterozygosity is calculated as 2pq, where p = frequency of allele A and q = frequency of allele B.
