Results from a three-locus, five-allele run of the simulation in which a rare mutant for OA mate choice was introduced into a CD population of 20,000 individuals. At generation 200, the mutation rate between CD and OA was set at 0.000001 per individual per generation. (a). Once established, the OA allele spread rapidly until it reached a frequency of about 0.8 in the population. (b) Frequency of the 1,1,1 host genotype. Note that in this version of the simulation there are a possible one hundred and twenty five host and parasite interaction genotypes.
