From: Are polymorphism and evolutionary rate of allozyme proteins limited by mutation or selection?
Nonequilibrium relationship between genetic distance and heterozygosity in a single-step mutation model. N is changed from 50 to 10 (contraction) or from 50 to 250 (expansion) after 260 generations and remains fixed at these new values. 4Nu=0.1; t=360; Ns=45, 25, 10, 5, 1, 0.1, 0. (a) Directional selection; A=0.04N, 4N, 400N. (b) Overdominance (open symbols) and underdominance (closed symbols). (Note that, unlike (Fig. 1) which has different symbols for different values of A, different symbols — squares, triangles and circles — are used here to illustrate the effects of the changing population size.)
