性隔离一直被认为是物种形成的主要原因之一，其遗传学研究有可能揭示物种形成的遗传学。在果蝇中，求爱歌曲在近亲物种之间性别隔离中的重要性已经得到了很好的研究，但分析与性别隔离相关的求爱歌曲差异的遗传基础的研究文献较少。果蝇和苍白果蝇由于其共域分布和没有交配后隔离，在性隔离研究中是有用的。众所周知，求爱歌曲在这两个物种之间的性别隔离中起着至关重要的作用，女性对求爱男性的歧视行为被发现是由第二条染色体上非常狭窄的区域控制的。在这项研究中，我们研究了控制与性别隔离相关的歌唱差异的遗传基础，使用了不同物种之间染色体替换的完整和无翼雄性。这些种间杂交雄性的结果表明，苍白粉蝶雌性所喜好的歌唱性状占优势。此外，从回交F2雄性中获得的结果表明，2号染色体对与性隔离相关的歌唱性状的控制起着主要作用。
Sexual isolation has been considered one of the primary causes of speciation and its genetic study has the potential to reveal the genetics of speciation. In Drosophila, the importance of courtship songs in sexual isolation between closely related species has been well investigated, but studies analysing the genetic basis of the difference in the courtship songs associated with sexual isolation are less well documented. Drosophila ananassae and Drosophila pallidosa are useful for studies of sexual isolation, because of their sympatric distribution and absence of postmating isolation. Courtship songs are known to play a crucial role in sexual isolation between these two species, and the female discrimination behaviour against the courting male has been revealed to be controlled by a very narrow region on the second chromosome. In this study we investigated the genetic basis controlling the song differences associated with their sexual isolation, using intact and wingless males with chromosomes substituted between species. The results obtained from F1 hybrid males between these species indicate the dominance of the song characters favoured by D. pallidosa females. In addition, the results obtained from backcross F2 males indicate that chromosome 2 had a major effect on the control of the song characters associated with sexual isolation.
