Digest: Male and female beetle genitalia are under stabilizing selection

摘要

The effect of selection on female genitalia is poorly studied, but such selection could affect mating success. House et al. (2020) studied the form and strength of selection acting on male and female Tribolium castaneum. They found that the sex organs of both male and female T. castaneum are under multivariate stabilizing selection and that both male and female genitalia interact to influence mating success.
