The cause of the high genetic variability in the major histocompatibility complex (MHC) is not entirely clear. Recently, two reports suggest that female mice prefer to mate with males different from them at the MHC. A model of female choice appropriate for those observations is developed here. Female choice can in fact reduce the observed proportions of homozygotes, maintain genetic polymorphism, influence mating-type frequencies and generate gametic disequilibrium.
