Locus fixation rates of allele A in the one-locus gametic SEIB model after 600 (a and b) and 3000 (c and d) years of evolution for different proportions of sexual reproduction P_S, different mutation rates and different seedling establishment probabilities P_E. Here, we only consider fixation of allele A, because allele a never went to fixation in the one-locus case. The x-axis is log scaled.
