果蝇simulans和果蝇mauritiana是兄弟物种，在它们的两个相互杂交中的一个中显示出实质性的性隔离。遗传分析表明，在女性中，这种隔离是由每个常染色体上至少一个隐性基因引起的，而X染色体几乎没有影响。我们的研究结果，与以前的研究相结合，表明在果蝇的性隔离的遗传学不同的合子后生殖隔离，这总是涉及到X染色体的大的影响。
Drosophila simulans and Drosophila mauritiana are sibling species that show substantial sexual isolation in one of their two reciprocal hybridizations. Genetic analysis reveals that in females this isolation is caused by at least one recessive gene on each autosome, while the X chromosome has little or no effect. Our results, combined with those of previous studies, show that in Drosophila the genetics of sexual isolation differs from that of postzygotic reproductive isolation, which invariably involves large effects of the X chromosome.
