Modeling assortative mating and genetic similarities between partners, siblings, and in-laws [PDF]
Nature Communications, 2022 Assortative mating could violate the assumption of random mating used in many genetic studies. Here, the authors study more than 25,000 Norwegian families to find genetic similarity between partners, siblings, and in-laws in genetic factors related to ...

Cross-trait assortative mating is widespread and inflates genetic correlation estimates [PDF]
Science, 2022 The observation of genetic correlations between disparate traits has been interpreted as evidence of widespread pleiotropy, altered theories of human genetic architecture, and spurred considerable research activity across the natural and social sciences.

Educational and age assortative mating in China: The importance of marriage order
Demographic Research, 2019 Background: Family change in China is characterized by increasing divorce rates and a growing number of remarriages, like in many Western countries. Assortative mating is a crucial part of the institution of (re)marriage and plays a key role in the (re ...

Assortative mating on blood type: Evidence from one million Chinese pregnancies. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance In the human population, spousal pairs have been found to share phenotypes, which demonstrates the highly nonrandom nature of human mate choice.

Estimation of indirect genetic effects and heritability under assortative mating
bioRxiv, 2023 Both direct genetic effects (effects of alleles in an individual on that individual) and indirect genetic effects — effects of alleles in an individual (e.g. parents) on another individual (e.g.

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 ...

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 ...
