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.
在许多动物中，雄性通常可以通过与许多配偶交配来提高其适应性，但雌性的后代数量不能超过其卵子的数量。尽管存在这种限制，雌性通常还是会与多个雄性交配。在没有任何雄性提供资源利益的物种中，雌性从雄性那里获得一些“遗传利益”，从而提高后代的质量。雌性多次交配的进化常常与雌性配偶选择的问题混淆，但在单次交配的情况下，配偶选择实际上是可能的。因此，我们仍然需要解释多次交配相对于单次交配的可能优势。
