Assortative Mating and Linkage Disequilibrium. [PDF]

G3: Genes, Genomes, Genetics, 2017
Assortative mating has been suggested to result in an increase in heritability and additive genetic variance through an increase in linkage disequilibrium.

Assortative mating biases marker-based heritability estimators [PDF]

Nature Communications, 2022
Methods for estimating heritability, the fraction of variance attributable to genetic factors, assume random mating. Here, the authors show that under assortative mating, when mate choice reflects phenotypic similarity, these methods produce ...

Assortative Mating Across the Full Spectrum of Mental Disorders: A Nationwide Finnish Register Study [PDF]

Biological Psychiatry Global Open Science
Background: Previous research has shown assortative mating across various psychiatric disorders; however, their definitions of partnership have often been limited, and the timing of relationship formation has been imprecise.

Genetic assortative mating for schizophrenia and bipolar disorder [PDF]

European Psychiatry, 2022
Background Psychiatric disorders are highly polygenic and show patterns of partner resemblance. Partner resemblance has direct population-level genetic implications if it is caused by assortative mating, but not if it is caused by convergence or social ...

The mechanism of assortative mating for educational attainment: a study of Finnish and Dutch twins and their spouses [PDF]

Frontiers in Genetics, 2023
Introduction: Assortative mating refers describes a phenomenon in which individuals with similar phenotypic traits are more likely to mate and reproduce with each other; i.e.

International Cross-Temporal Meta-Analysis of Assortative Mating for Educational Attainment [PDF]

Evolutionary Psychology
Previous studies have found a high degree of assortative mating for educational attainment (r = .56). However, this can be confounded by cohort effects or country effects, where certain nations may have more pronounced assortative mating than others.

Genetic similarity between relatives provides evidence on the presence and history of assortative mating [PDF]

Nature Communications
Assortative mating – the non-random mating of individuals with similar traits – is known to increase trait-specific genetic variance and genetic similarity between relatives.

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 ...
