In the last decades, conventional patterns of assortative mating have been challenged by changes in the gender-gap in education. In many countries, educationally unions (i.e. the woman is more educated than the man) now outnumber unions (i.e. the man is more educated than the woman). The extent to which such structural changes have also been accompanied by gender egalitarian attitudes has not yet been investigated. This paper fills the gap by focusing on both age and educational assortative mating, using data from wave 1 and 2 of the Generations and Gender Surveys for 6 European countries. I investigate the role of gender-role attitudes of single men and women, measured in the first wave, on their age and educational assortative mating outcomes observed in the second wave. To this aim, I applied multinomial logistic regressions, and used as reference outcome category in the second wave. Compared to non-egalitarian men, I found that men holding gender-egalitarian views are more likely to form hypogamous unions instead of remaining single, in terms of both age and educational assortative mating. Egalitarian women are more likely than non-egalitarian women to form age-hypogamous unions instead of remaining single, but they are less likely to form educationally hypogamous unions. I discuss the implications of these results in relation to the convergence of mating preferences between men and women.

Adaptive divergence and increased genetic differentiation among populations can lead to reproductive isolation. In Lake Constance, Germany, a population of invasive three-spined stickleback () is currently diverging into littoral and pelagic ecotypes, which both nest in the littoral zone. We hypothesized that assortative mating behaviour contributes to reproductive isolation between these ecotypes and performed a behavioural experiment in which females could choose between two nest-guarding males.

Socioeconomic status (SES) impacts health and life-course outcomes. This genome-wide association study (GWAS) of sociologically informed occupational status measures (ISEI, SIOPS, CAMSIS) using the UK Biobank (N = 273,157) identified 106 independent single-nucleotide polymorphisms of which 8 are novel to the study of SES. Genetic correlations with educational attainment (r = 0.

Species-specific sexual traits facilitate species-assortative mating by reducing mating across species and reducing hybrid sexual attractiveness. For learned sexual traits, such as song in oscine birds, species distinctiveness can be eroded when species co-occur. Transcriptional regulatory divergence in brain regions involved in sensory learning are hypothesized to maintain species distinctiveness, but relatively few studies have compared gene expression in relevant brain regions between closely related species.
