在与黑腹果蝇的多次交配中，每只苍蝇携带不同的显性标记基因，这表明雄性对下一代的贡献比雌性更具变异性。这是由于男性内部的选择，而这又是因为男性的生育能力更多地依赖于受精的频率。这被证明是性别分化的直接结果。因此，在动物王国，甚至植物界，性内选择几乎仅限于雄性。
Multiple matings with D. melanogaster in which each fly carries a different dominant marker gene show that the contribution of males to the next generation is more variable than that of females. This is due to intra-masculine selection which in turn results from the greater dependence of the fertility of males on frequency of insemination. This is shown to be a direct result of sexual differentiation. Hence intra-sexual selection is almost confined to males in the animal and even plant kingdoms.
