  1. P values are shown for two-sided Wilcoxon rank-sum tests for differences in heterozygosity (H e ) between microsatellites with different repeat unit sizes. Loci are grouped by whether they had one or two separate STR regions. No comparisons were made for loci with three separate STR regions because of small sample size for di-nucleotide and tri-nucleotide loci (3 and 2, respectively). Tests with P < 0.05 are highlighted in bold.
