Abstract

Females in many species bias fertilization success and paternity after mating with multiple males. Two new studies uncover the mechanisms of this phenomenon, cryptic female choice, in Drosophila, linking it to pheromone-stimulated ejection of sperm and mating plug.

摘要

在许多物种中，雌性在与多个雄性交配后会偏向于成功受精和获得亲代。两项新的研究揭示了这种现象（隐秘的雌性选择）在果蝇中的机制，将其与信息素刺激的精子排出和交配栓联系起来。
