Abstract: | Background When females mate with multiple partners, sperm from rival males compete to fertilise the ova. Studies of experimental evolution
have proven the selective action of sperm competition on male reproductive traits. However, while reproductive traits may
evolve in response to sperm competition, this does not necessarily provide evidence that sperm competitive ability responds
to selection. Indeed, a study of Drosophila failed to observe divergence in sperm competitive ability of males in lines selected for enhanced sperm offence and defence. |
