Abstract
I present a model of chiasma interference and recombination in homo- and heterokaryotypes and a model of nonrandom mating. These two models form the basis of a general-purpose deterministic multilocus evolution simulator, which I use to show how chromosomal inversions can enhance and accelerate reinforcement in various scenarios. I conclude that an inversion can initiate a snowball effect of increasing pre- and postzygotic isolation, even when there is some recombination in heterokaryotypes.
