P values are shown for two-sided Wilcoxon rank-sum tests for differences in heterozygosity (He) between microsatellites with one, two, or three separate STR regions. Loci are grouped by their repeat unit size. For di-nucleotide and tri-nucleotide loci, because of small sample size (3 and 2, respectively), the column for three separate STR regions was omitted. Tests with P < 0.05 are highlighted in bold.
