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 کاملModels of Cultural Niche Construction with Selection and Assortative Mating
Niche construction is a process through which organisms modify their environment and, as a result, alter the selection pressures on themselves and other species. In cultural niche construction, one or more cultural traits can influence the evolution of other cultural or biological traits by affecting the social environment in which the latter traits may evolve. Cultural niche construction may i...
متن کاملReply to Lee: Spatial sorting, assortative mating, and natural selection
Lee (1) suggests that spatial sorting will be important only under limited circumstances, that it may often affect traits also subject to natural selection, and that it will enhance the effectiveness of selection by increasing phenotypic variance via positive assortative mating. These points build on the arguments advanced in our original paper, and we broadly agree with him. First, Lee (1) sug...
متن کاملFrequency-dependent selection and the evolution of assortative mating.
A long-standing goal in evolutionary biology is to identify the conditions that promote the evolution of reproductive isolation and speciation. The factors promoting sympatric speciation have been of particular interest, both because it is notoriously difficult to prove empirically and because theoretical models have generated conflicting results, depending on the assumptions made. Here, we ana...
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...
