  1. Five of the markers consist of exons only, while the remaining four markers consist of a combination of exons and introns. Analyzed fragments are shorter than amplified markers, because indels, VNTRs, and some poor sequences were deleted prior to data analysis. *, **, and *** indicate the significance of Tajima's D test at p ≤ 0.05, p ≤ 0.01, and p ≤ 0.001 (respectively).
