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.

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.
