  1. N = sample size per population; n = mean sample size over all loci; P = proportion of polymorphic loci; A = mean number of alleles per locus; Ar = mean number of alleles standardized to the smallest sample. He = unbiased expected heterozygosity standardized according to the (2N/2N-1)*He) formula; Ho = observed heterozygosity, Lat is the latitude (N) and Long is the longitude (W).
