  1. a Sites = number of nucleotides in each gene or segment region. S = number of segregating sites. Hap = number of distinct haplotypes. ηe = number of singletons, π = nucleotide diversity, the average number of nucleotide differences per site between two sequences, πs = nucleotide diversity among synonymous sites, πs = nucleotide diversity among replacement sites, θ = E(π expected number of pairwise differences in S, F* = Fu and Li (1993). * |F*| > 0 with probability of 0.05, ** |F*| > 0 with probability of 0.01
