研究了近缘的两种异域种果蝇（Drosophila nasuta和D. Albomicans，没有进化出性（交配前）隔离。几个后合子组件的健身内和种间杂交进行了分析。结果表明，这两个物种是生殖隔离的，因为它们是不同的共适应系统。在D.此外，还发生了遗传分化。D. Albomicans讨论。
Genetic divergence was investigated between 2 closely related allopatric species, Drosophila nasuta and D. albomicans, which have not evolved sexual (pre-mating) isolation. Several post-zygotic components of fitness were analysed in intra- and interspecific hybrids. The results show that these 2 species are reproductively isolated because they are different co-adapted systems. Among geographic populations of D. albomicans, genetic differentiation has also occurred. The evidence for primary subspeciation in D. albomicans is discussed.
