Unbiased intra-population genetic diversity indices independent of allele frequency.

Average percent difference (APD) and standard error (SE) are reported by population for β-Fibr intron and ELA loci. APD was estimated by pair-wise comparisons of all individuals in a population, with C equal to the number of comparisons made at each locus [72]. Chi-square (χ2) and Z statistics are reported for Kruskal-Wallis (K-W) rank randomization and Wilcoxon tests, respectively. Significant rejection (p<0.05) of the null hypothesis of group mean equality is indicated in boldface. Estimates for the DQA locus are reported both excluding (DQA) and including (DQAALL) individuals with multi-locus genotypes.
