Abstract

Let w 1, w 12 and w 2 be the fitnesses of genotypes A 1 A 1, A 1 A 2 and A 2 A 2 in an infinite diploid population, and let pn be the A 1, gene frequency in the nth generation. If fitness varies independently from generation to generation, then pn is a Markov process with a continuum of states. If E[In(wi /w 12)] < 0 for i = 1, 2, then there is a unique stationary probability, and the distribution of pn converges to it as n → ∞.
