Fst: Wright’s F-statistics, pairwise genetic distance [22], Nm: Gene flow and population migration among populations [22, 23], Kxy: Average proportion of nucleotide differences between populations. Dxy: The average number of nucleotide substitutions per site between populations [20], Da: The number of net nucleotide substitutions per site between populations [20], Gst: Genetic differentiation index based on the frequency of haplotypes [24].
