在果蝇sechellia，女性接受男性唱异种歌曲比那些不唱歌，而在D。melanogaster和D.同样，雌性接受唱异种歌曲的雄性比那些不唱歌的雄性更容易。在这里，我们研究了D的性隔离。sechellia及其兄弟姐妹利用种间杂种揭示雌性配偶识别的机制。杂种雌虫与亲本有翅雄虫的交配次数多于与无翅雄虫的交配次数，表明黑腹叶蝉对异种鸣叫的辨别能力与雌虫的交配次数有关。sechellia雌性是隐性的。雌性对求偶歌的偏好似乎是附加或半显性遗传的。此外，我们研究了女性的感受性，没有求爱歌曲的刺激，通过比较交配频率之间的十字架使用无翅男性，发现它也是遗传的加性或半显性。
In Drosophila sechellia, females accept males that sing heterospecific songs less than those that do not sing, whereas in D. melanogaster and D. simulans, females accept males that sing heterospecific song more than those that do not sing. Here we studied the sexual isolation of D. sechellia and its siblings using interspecific hybrids to reveal the mechanisms underlying female mate recognition. The females of hybrids mated more with winged males of the parent species than with wingless ones, suggesting that the discrimination against heterospecific songs by D. sechellia females is recessive. Female preference for courtship songs seems to be inherited additively or semidominantly. In addition, we examined female receptivity without the stimuli of courtship songs by comparing the mating frequencies between the crosses using wingless males and found that it is also inherited additively or semidominantly.
