Cryptic female choice
Cryptic female choice is a form of mate choice which occurs both in pre and post copulatory circumstances when females in certain species use physical or chemical mechanisms to control a male's success of fertilizing their ova or ovum; i.e. by selecting whether sperm are successful in fertilizing their … See more Females not only exert sexual control but also benefit from exerting such control over male reproductive success.
