title: Equilibrium stability of a diffusion process in population genetics.
abstract: De Finetti introduced a model of a continuously reproducing population with phenotypic assortative mating for a pair of dominant-recessive autosomal genes. In this paper it is rigorously proved that this model admits of stable equilibria which lie above the Hardy--Weinberg parabola in the de Finetti diagram.
