Ho: mean observed population heterozygosity rate; He: mean expected population heterozygosity rate from the Hardy–Weinberg equation.
F: mean population inbreeding coefficient, calculated as F=(He−Ho)/He. The mean SNP heterozygosity rate for each individual was calculated using Haploview. The mean heterozygosity rate was then calculated for each population.
Common: SNPs were found in all five populations; Pruned: those SNPs remaining when SNPs in high LD with an adjacent SNP (r2>0.5) were removed.
