Assortative mating without assortative preference [PDF]
Proceedings of the National Academy of Sciences, 2015 Significance Assortative mating, the tendency of men and women who marry to have similar social characteristics, is a commonly observed phenomenon in human societies. This study shows that assortative mating could result from structural causes independent of human agents’ preference, because unmarried persons who newly enter marriage are ...

Conditioning on parental mating types can reduce necessary assumptions for Mendelian randomization
Frontiers in Genetics, 2023 Mendelian randomization (MR) has become a common tool used in epidemiological studies. However, when confounding variables are correlated with the instrumental variable (in this case, a genetic/variant/marker), the estimation can remain biased even with ...

Can preference for oviposition sites initiate reproductive isolation in Callosobruchus maculatus? [PDF]
PLoS ONE, 2011 Theory has identified a variety of evolutionary processes that may lead to speciation. Our study includes selection experiments using different host plants and test key predictions concerning models of speciation based on host plant choice, such as the ...

The genetic correlation between height and IQ: shared genes or assortative mating? [PDF]
PLoS Genetics, 2013 Traits that are attractive to the opposite sex are often positively correlated when scaled such that scores increase with attractiveness, and this correlation typically has a genetic component.

Assortative Mating By Diet In A Phenotypically Unimodal But Ecologically Variable Population Of Stickleback [PDF]
, 2008 Speciation with gene flow may be driven by a combination of positive assortative mating and disruptive selection, particularly if selection and assortative mating act on the same trait, eliminating recombination between ecotype and mating type ...

Assortative Mating on Ancestry-Variant Traits in Admixed Latin American Populations
Frontiers in Genetics, 2019 Assortative mating is a universal feature of human societies, and individuals from ethnically diverse populations are known to mate assortatively based on similarities in genetic ancestry. However, little is currently known regarding the exact phenotypic

Size-assortative mating in simultaneous hermaphrodites: an experimental test and a meta-analysis [PDF]
, 2015 Assortative mating by size has been argued to be widespread in the animal kingdom. However, the strength of size-assortative mating is known to vary considerably between species and the underlying mechanisms promoting this inter-specific variation remain

Assortative mating in Gastropoda: A meta-analysis
Biosystems Diversity, 2023 The term ‘assortative mating’ denotes situations when the choice of a mating partner is nonrandom and the phenotypes across mate pairs are correlated, either positively or negatively.
