AA, DD, and AD represent a homozygote of an ancestral allele, a homozygote of a derived allele, and a heterozygote of ancestral/derived alleles, respectively. H_obs and H_exp indicate an observed and expected heterozygosity, respectively. HWE indicates the Hardy-Weinberg equilibrium, and those values are the probabilities that did not deviate from the HWE.
