A STUDY OF SEXUAL ISOLATION BETWEEN CERTAIN STRAINS OF DROSOPHILA PAULISTORUM
@article{MalogolowkinCohen1965ASO, title={A STUDY OF SEXUAL ISOLATION BETWEEN CERTAIN STRAINS OF DROSOPHILA PAULISTORUM}, author={C. Malogolowkin-Cohen and A. S. Simmons and H. Levene}, journal={Evolution}, year={1965}, volume={19} }
The superspecies Drosophila paulistorum Dobzhansky and Pavan consists of six races or incipient species which exhibit various degrees of reproductive isolation from each other. The two principal isolating mechanisms involved are sexual (ethological) isolation and sterility of hybrid males (Dobzhansky and Spassky, 1959; Dobzhansky et al., 1964). Sexual isolation is almost certainly the more effective of the two mechanisms in preventing gene exchange between the incipient species in their natural… Expand
