Assortative 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 کاملEvolution of disassortative and assortative mating preferences based on imprinting.
A two-locus haploid model of sexual selection is investigated to explore evolution of disassortative and assortative mating preferences based on imprinting. In this model, individuals imprint on a genetically transmitted trait during early ontogeny and choosy females later use those parental images as a criterion of mate choice. It is assumed that the presence or absence of the female preferenc...
متن کاملAssortative Mating and Linkage Disequilibrium
Assortative mating has been suggested to result in an increase in heritability and additive genetic variance through an increase in linkage disequilibrium. The impact of assortative mating on linkage disequilibrium was explicitly examined for the two-locus model of Wright (1921) and two selective assortative mating models. For the Wright (1921) model, when the proportion of assortative mating w...
متن کاملAssortative mating and affective disorders.
Seventy-two spouses of subjects with recurrent primary affective disorders (PAD), were investigated for the presence of psychiatric disorders in their lives and in those of their first degree relatives, and compared with 71 spouses of non-psychiatrically ill control subjects. No difference was found in the risk for PAD; on the other hand spouses of affective patients manifested a greater occurr...
متن کاملAssortative mating based on phenotype. I. Two alleles with dominance.
I N animals with separate sexes several traits are known to induce some sort of preference for mating between similar individuals (assortment) or preference for mating between dissimilar individuals (disassortment) . Assorting, for example, is known to occur in certain bird, mammal (man included) and insect populations. Traits affecting preferences can be partly subject to environmental control...
