Males and females experience divergent selection on many shared traits, which can lead to 'sexual antagonism' - opposing fitness effects of genetic variants in each sex. A new study in the fly Drosophila serrata links sexually antagonistic selection on cuticular hydrocarbons to a single major-effect gene.

Sexual sadism has long been of interest to scholars and clinicians in psychology, and most research on sexual sadism has focused on forensic samples. However, recently, research has uncovered the existence of sexual sadism in general populations. Measures designed to assess sexual sadism in the general population are lacking.

Recombination plays a key role in increasing the efficacy of selection. We investigate whether recombination can also play a role in resolving adaptive conflicts at loci coding for traits shared between the sexes. Errors during recombination events resulting in gene duplications may provide a long-term evolutionary advantage if those loci also experience sexually antagonistic (SA) selection since, after duplication, sex-specific expression profiles will be free to evolve, thereby reducing the load on population fitness and resolving the conflict.

Oocyte-secreted factors (OSFs), such as BMP15 and GDF9, are soluble paracrine factors that drive cumulus cell differentiation and function, sustaining oocyte competence acquisition and embryo development. This study aimed to assess the effect of BMP15 and GDF9 on IVM medium of prepubertal goat oocytes. COCs were in vitro matured in absence (control group) or presence of 100 ng/mL of BMP15, GDF9, or both.

When different alleles are favored in different environments, dominance reversal where alternate alleles are dominant in the environment in which they are favored can generate net balancing selection. The sexes represent two distinct genetic environments and sexually antagonistic (SA) selection can maintain genetic variation, especially when the alleles involved show sex-specific dominance. Sexual dimorphism in gene expression is pervasive and has been suggested to result from SA selection.

In eutherians, one of the X chromosomes in each cell of the early female embryo is rendered transcriptionally silent through X chromosome inactivation. The choice of which X chromosome to inactivate takes place independently in each cell and is stably inherited through development, leading to a roughly 50:50 ratio of cells in the adult body expressing one or the other X chromosome. However, X chromosome inactivation can be skewed, with certain X chromosomes showing a heritable tendency to avoid inactivation.
