By Benjamin Padilla-Morales, Postdoctoral Researcher of Bioinformatics, University of Bath

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual selection is where individuals with certain traits have higher reproductive success, leading to the spread of those traits throughout a species.
