title: Comments on the Penrose-Stanton model of assortative mating.
abstract: A single-locus model of assortative mating proposed by Penrose and extended by Stanton is analysed. It is shown that the formulae giving values of correlations between males and relatives derived by Stanton apply to a general class of symmetric, non-selective mating schemes in equilibrium when genotypes have additive values. The canonical form of Stanton's system is derived, revealing that the assignment of additive values of genotypes does not apply also to the canonical vectors.
