Figure P22.4. Fitnesses of F₁ males (red) and F₁ females plotted against the number of substitutions in each lineage. The chance of a pair of alleles being incompatible is p = 10^–3, causing a reduction in fitness s = 10% if the incompatibility is expressed; 20% of substitutions are on the X, and the chance of an allele being dominant is α = 1%.
