(Phys.org) -- The study of “sexual conflict” between males and females helps us to understand why sexual reproduction persists given that it can be costly, especially to females. One aspect of this conflict concerns how females respond to increased mating events that are of more benefit to males than to themselves. This work on traumatic insemination was conducted by Umea University researcher Tom Cameron together with colleagues at the University of Leeds. The results have been published in Biology Letters.
