In the interest of better understanding the differences between sexes, we have studied sexual selection and conflict. We did so in two ways:
I- Parthenogenetic species produce mainly daughters without males. We study selection during the rare events of sexual reproduction in Daphnia.
II- Seminal fluid proteins are generally considered male tools to manipulate females. We investigated the growing hypothesis that seminal fluid proteins are important signals for females to adjust their egg-laying and mating decisions, and thus help reduce sexual conflict.
