在许多动物中，雄性通常可以通过与许多配偶交配来增加他们的健康，但雌性不能产生比它们的卵子数量更多的后代。尽管有这样的限制，雌性经常与不止一只雄性交配。在没有雄性提供任何资源优势的物种中，雌性被认为从雄性那里获得了一些提高后代质量的“遗传利益”。女性多次交配的进化经常与女性选择配偶的问题混淆，但在单次交配的情况下，择偶实际上是可能的。因此，我们仍然需要解释多次交配比单次交配可能具有的优势。
In many animals, males can generally increase their fitness by mating with many mates, but females cannot produce more offspring than the number of their eggs. In spite of this restriction, females often mate with more than one male. In species without any male-provided resource benefits, females are thought to obtain some 'genetic benefits' from males that enhance offspring quality. The evolution of female multiple mating is often confused with the issue of female mate choice, but mate choice is actually possible in the single-mating situation. Therefore, we still need to explain the possible advantage of multiple mating over single mating.
