Gut length driven by 'sexual conflict' in fish species

A new study that looked at gut length variation between cichlid fish species found that some of the genetic loci for the trait are sex-specific even though males and females of the same species have the same gut length. The work supports a scenario of "sexual conflict," where gut length differences evolved under different pressures for males and females of the same species and could have implications for the understanding of gut length evolution more generally.
