Behavioural genetics is the interdisciplinary effort to establish causal links between genes and animal (including human) behavioural traits and neural mechanisms. Methods used include twin ...

A longstanding question in evolutionary biology is how sexual selection influences how entire genomes develop. Sexual ...

suggesting that they may have been less compatible with the majority genetic background. This hints at a process known as purifying selection, where natural selection removes harmful mutations over ...

Studies have suggested that genes under strong sexual selection tend to evolve rapidly, particularly those associated with male reproductive traits, such as body size or colour. Additionally, genomic ...
