Figure 2.—
Frequency distribution of deleterious mutations in linkage with S-alleles i (ϕi) belonging to different dominance classes (dominant, intermediate, or recessive). Five S alleles and three dominance classes were assumed, with two alleles in the most dominant and the intermediate classes and one allele in the most recessive class. Since the two alleles in a given dominance class are selectively equivalent, their frequency distributions are identical and only one frequency distribution by dominance class is shown. Parameters values: N = 1000, s = 0.1, h = 0, μ = 10−4, and η = 10−5.
