The absolute frequencies of one, two, or three alleles (a, b, c) are given for each locus. HET is the expected heterozygosity for each locus in each sample. n is the average sample size. Fst measures the differentiation between the different samples of the same continent and was estimated as Fst = {HT – (ΣHi)/ns}/HT, where ns is the number of samples, Hi is the expected heterozygosity within sample i, and HT is the total heterozygosity. This estimator is not unbiased but gives an idea of the amount of differentiation between samples within continents.
