Min (kij) refers to the minimum number of interspecific pairwise nucleotide differences per locus (an estimator of τ), while d12 is the average number of pairwise (interspecific) differences. The final column presents d12 estimates on a per-site basis, with the weighted average value given in the “Total” row. These analyses were based on the total data set comprising all four populations per species. From these data, we calculated the ancestral population size as θA = d12 − min (kij).
