Limiting Distribution under Assortative Mating*
A multi-locus model for complete positive assortative mating is discussed. For a two-locus model, if the gene frequencies for the two loci are different, as they are likely to be, it is shown that in equilibrium the population is not composed of only two homozygous types, as is usually thought. The limiting distribution will have three homozygous genotypes depending upon the initial gene freque...
متن کاملQuantitative characters under assortative mating: gametic model.
The gametic model introduced by Gimelfarb (1982, Theor. Pop. Biol. 22, 324-366) is applied to investigating the dynamics, represented in the model by a second-order recurrence equation, the the variance of sex-independent and sex-controlled characters under assortative mating. It is shown that, for any additive character, there always exists a unique equilibrium for the variance, which is stabl...
متن کاملAssortative mating without assortative preference.
Assortative mating--marriage of a man and a woman with similar social characteristics--is a commonly observed phenomenon. In the existing literature in both sociology and economics, this phenomenon has mainly been attributed to individuals' conscious preferences for assortative mating. In this paper, we show that patterns of assortative mating may arise from another structural source even if in...
متن کاملFurther analysis of negative assortative mating.
HE paper “Ana1ys.k of models with homozygote x heterozygote matings“ was devoted to the complete mathematical analysis of the equilibrium behavior of some models proposed by SCUDO (1964) and FINNEY (1952) and some of their qualitative implications for population genetics in general. In this paper we repeat this process with certain models described by WORKMAN ( 1964), NAYLOR (1962) and others. ...
متن کاملA note on the generalized effects of assortative mating.
Several twin studies of multiple abilities and educational and socioeconomic variables suggest that a single common factor underlies the contribution of mate selection and cultural inheritance to the covariation of such measures. Theoretical analysis shows that this finding is consistent with a mechanism of mate selection in which specific abilities are merely components of a composite latent v...
