Haplotype no. is the number of distinct haplotypes; haplotype diversity is a measure of expected heterozygosity; haplotype sharing represents the fraction of haplotypes in one population that are also found in the other; F_ST represents between group diversity. Data are medians of the 1,000 simulations performed for each evolutionary scenario. The simulated parameters that differed significantly from the observed values (see Table 2) are in italics.
