Evolutionary dynamics of hot-spot S2. Simulations were performed on populations each seeded 70,000 years ago with a single S9.1A->G mutation, then allowed to evolve by random mating with crossovers occurring in S9.1A/G heterozygotes at the mean frequency seen in sperm and assuming no female crossover activity (sex-averaged crossover rate of 0.083%). Transmissions into crossover progeny were biased against S9.1G at the mean level seen in sperm crossovers (A:G 0.743:0.257). Four examples of simulations that achieved the contemporary S9.1G frequency of 3.4% (circle) are shown (solid lines). Simulations into the future (dashed lines) used the same population and crossover parameters.
