What is post copulatory mating?

Post-copulatory mating refers to behaviors and processes that occur after sperm transfer during copulation, often aimed at enhancing reproductive success. This can include mechanisms such as sperm competition, where males may engage in various strategies to ensure their sperm fertilizes the eggs, as well as female choice behaviors that can influence which sperm succeeds. Such interactions are important in evolutionary Biology, as they can affect mating systems and reproductive strategies within different species.
