From: Are polymorphism and evolutionary rate of allozyme proteins limited by mutation or selection?
Relationship between heterozygosity and genetic distance for overdominance in a single-step mutation model. 4Nu=0.01, 0.1, 0.2; N=50; t=360; Ns=45, 25, 10, 5, 1, 0.1, 0. (a) Single-step with gene flow (Nm=0.5, where m is migration rate); results for Nm=0 are shown for comparison. (b) Periods of overdominance and neutrality alternate in each replicate (probability of shift between the two modes of selection determined by parameter A=4N).
