Comparison of sampling by sex and by asex in the multi-locus haploid model for different population sizes. The simulation conditions are as described in Fig. 3, except that now the population size varies on the x-axes and only two recombination rates values are used, r=0 (asex, cyan solid line; 95% C.I. cyan dashed lines) and r=0.5 (sex, blue solid line; 95% C.I. blue dashed lines). The probability that the more mixable allele across all possible genotypes was favored, P, is markedly higher in the sexual case. Furthermore, as the population size is increased, P increases in the sexual population but not in the asexual one. This figure shows that with increasing population size, selection for mixability becomes stronger only in the sexual population
