Figure 6.—
Average frequencies for the four classes of fully functional alleles, as a function of effective population size for three mutation ratios (all with μa + μd = 0.0005 and μc = 0.0001) and as a function of the mutation ratio for infinite populations (see appendix for derivation). In the latter case, the equilibrium frequencies depend only on the ratio of mutation rates, not on their absolute values (bottom right).
