The genetic factors involved in the sexual isolation between Drosophila simulans females and D. melanogaster males are hardly known. We present a study of female mating propensity of D. simulans from different geographic origins with D. melanogaster males. Our results reveal the existence of genetic variability in D. simulans for this trait. Female discrimination is dominant against high female interspecific mating, which differs from that detected in other Drosophila species crosses.
关于拟暗果蝇雌蝇和黑腹果蝇雄蝇之间性隔离所涉及的遗传因素几乎一无所知。我们对来自不同地理起源的拟暗果蝇雌蝇与黑腹果蝇雄蝇的雌性交配倾向进行了一项研究。我们的结果揭示了拟暗果蝇在这一性状上存在遗传变异性。雌性歧视对于高频率的种间雌性交配具有主导作用，这与在其他果蝇物种杂交中检测到的情况不同。
