在一些生物体中，雄性精子在多次授精的雌性体内的成功取决于雄性的基因型。在果蝇中，雌性在决定哪个精子成功方面也起着作用。对黑腹果蝇的6个等基因系进行了两两测试，以确定精子的成功是否存在基因型特异性相互作用。研究发现，特定雄性精子的成功与否取决于与之交配的雌性的基因型，这为一种具有深远进化影响的相互作用提供了证据。
In several organisms, the success of a male's sperm in multiply inseminated females depends on the male's genotype. In Drosophila, the female also plays a role in determining which sperm are successful. Pairwise tests among six isogenic lines of Drosophila melanogaster were performed to determine whether there is a genotype-specific interaction in the success of sperm. The success of a particular male's sperm was found to depend on the genotype of the female with which he mates, providing evidence for an interaction with profound evolutionary consequences.
