  1. Dominance values d is defined as difference between heterozygotes and the mean of the two homozygous genotypes. Regarding the promoter VNTR alleles, heterozygotes characterized by having one copy of the respective allele are compared to the mean of the groups of individuals with zero or two copies representing the alternative homozygous genotypes. ap-values are given as indices.
