  1. N is the number of individuals analyzed. Npl, Nm, HO, HE stand, respectively, for the number of polymorphic loci, the mean number of alleles, the mean observed heterozygosity and Nei’s unbiased gene diversity over all loci. Their standard errors are indicated in parentheses. f̂ is the estimate of Wright’s FIS and ŝ the estimate of the selfing rate derived from f̂. ŝ′ is the estimate of the selfing rate based on the method of David et al. (2007).
