Dominance variance in Fisher's model of assortative mating.

It is argued that there is some confusion in the literature concerning the effect of assortative mating on dominance variance. It is shown that in Fisher's model of assortative mating additive deviations of one factor are correlated with additive deviations of another and that this correlation is responsible for the increase in genetic variance. The dominance deviations of one factor are independent of the dominance, as well as of the additive deviations of a second factor. It is shown that in Fisher's model of assortative mating and to the approximation used by him, the dominance variance does not change under assortative mating.

Assortative mating, linkage and genotypic frequencies.

The effect of introducing assortative mating in a population in linkage equilibrium is considered. It is shown that the introduction of assortative mating will disturb linkage equilibrium which will be re-established at another point independent of the recombination value r but depending upon additive variance and gene frequencies. It is also shown that when equilibrium is established Fisher's (1918) model of assortative mating will be applicable.
