Brief communication. Inheritance mode of Drosophila simulans female mating propensity with D. melanogaster males
The genetic factors involved in the sexual isolation between Drosophila simulans females and Drosophila melanogaster males are hardly known. We present a study of female mating propensity of Drosophila simulans from different geographic origins with Drosophila melanogaster males. Our results reveal the existence of genetic variability in Drosophila simulans for this trait. Female discrimination is dominant against high female interspecific mating, which differs from that detected in other Drosophila species crosses.
