理论模型预测，性冲突可以通过降低来自异地种群的个体之间的交配概率来驱动生殖隔离。最近对粪蝇的一项研究支持了这一预测。为了测试这一发现的普遍性，我们使用了在高、中、低水平的性冲突下选择的黑腹果蝇的复制品系，其中雌性果蝇对雄性诱导的伤害的抵抗水平有所不同。我们比较了在设定的时间点交配的处女对的比例，对于来自每个性冲突水平内的相同重复的苍蝇与来自每个性冲突水平内的不同重复的苍蝇。结果不支持D.性冲突通过改变雌性的交配意愿来驱动种群分化。这些结果不太可能被解释为近亲繁殖的差异或对性冲突缺乏反应。
Theoretical models predict that sexual conflict can drive reproductive isolation by decreasing the probability of matings between individuals from allopatric populations. A recent study in dung flies supported this prediction. To test the generality of this finding we used replicate lines of Drosophila melanogaster that had been selected under high, medium and low levels of sexual conflict, in which the females had evolved differences in their level of resistance to male‐induced harm. We compared the proportion of virgin pairs that mated by set time points, for flies from the same replicate within each sexual conflict level vs. flies from different replicates within each sexual conflict level. The results did not support the prediction that, in D. melanogaster, sexual conflict drives population divergence via changes in female willingness to mate. The results were unlikely to be explained by differential inbreeding or by a lack of response to sexual conflict.
