From: Are polymorphism and evolutionary rate of allozyme proteins limited by mutation or selection?
Relationship between genetic distance and heterozygosity for directional selection in a single-step mutation model with homozygote fitness values fluctuating between 1 and 1−s. A=0.04N, 4N, 400N; 4Nu=0.01, 0.1, 0.2. Each plotted point is based on 1000 replicate loci (see text). Values of Ns are shown adjacent to many of the plotted points, and can be inferred for other well separated points that are unlabelled. (a) N=50; t=360; Ns=45, 25, 10, 5, 1, 0.1, 0. (b) N=250; t=1700; Ns=225, 45, 1, 0; 4Nu=0.1 (4Nu=0.01, 0.2 not simulated). (c) Parameter values as in (a) but with t=40.
