Using Sex-Specific Robertson Covariances to Estimate Within- and Cross-Sex Responses to Selection on Reproductive Traits in Drosophila melanogaster | The American Naturalist

This seems rad: overexpressing FruM in a set of proboscis-motorneuron-projecting neurons makes melanogaster males add food-sharing to their courtship repertoire.
It is fascinating to see evolutionary shifts in behavior be tied so concretely to shifts in brain development!

Molecular and genomic insights to sexually antagonistic genes (GRIESHOP_U26DTP) | Doctoral Training Partnership
Why do harmful genes persist in populations instead of being removed by natural selection? One answer lies in sexual antagonism: when a genetic variant benefits males but harms females, or vice versa.
