  • In all the simulations, the selection coefficient s equals 0.03, and the genomic mutation rate U equals 1, which approximates those from mutation accumulation experiments (Mukai et al. 1972; Kibota and Lynch 1996) without assuming dominance or overdominance. Throughout, the numbers reported are the means and standard deviations (SDs, numbers within parentheses) over 100 simulations; a SD of 0.000 indicates a SD <0.0005.
