  • S, segregating sites; K, haplotypes; H, haplotype diversity, defined as the probability that two alleles randomly chosen from the population are different. π was calculated using the Jukes–Cantor correction (Jukes and Cantor 1969, Lynch and Crease 1990); θ was calculated using the total number of mutations rather than the number of segregating sites (Tajima 1996). π and θ were estimated for the following categories of nucleotide sites/regions: total (πT, θT), nonsynonymous (πn, θn), synonymous (πs, θs), intron (πi, θi), UTR (πU, θU). For loci with two introns, values for πi and θi are averages.
