N, Number of Individual sampled; P, Proportion of polymorphic loci; Ho, observed heterozygosity; He, Hardy-Weinberg expected heterozygosity; Fis, Inbreeding coefficient over the 21 loci. Significant test for departure from Hardy-Weinberg Equilibrium are indicated as ns for P > 0.1, (*) for P < 0.1, * for P < 0.050; ** for P < 0.010 and *** for P < 0.001. m, Monomorphic.
