  • “Inbred?,” whether individual genotypes were scored after laboratory inbreeding (“i,” inbred strains) or without (“h,” potentially heterozygous); “N,” number of genotyped individuals; “Pairwise difference,” mean number of different pairwise microsatellite loci; “H,” gene diversity (calculated with Arlequin; Excoffier et al. 2005) and its standard deviation (SD); “Θhom,” Θ-parameter calculated after homozygosity and its standard deviation; f, equilibrium inbreeding coefficient (estimator of FIS after Weir and Cockerham 1984, calculated with GDA; Lewis and Zaykin 2001) and its 95% confidence interval (C.I.); s, selfing rate calculated after f and its 95% confidence interval.
