Crosses between Drosophila virilis and D. texana produce viable and fertile F-1 males and females. When F-1 males are backcrossed to either parental species they also produce fertile sons. However, about one-third of F-1 males carrying the D. texana Y chromosome are sterile. When fertile F-1 males with the D. texana Y chromosome are crossed to D. virilis, about three quarters of the sons are sterile. We show that these sterilities result from incompatibilities between the D. texana Y chromosome and at least two of the D. virilis autosomes. X/Y incompatibilities can be excluded in this pair of species, and X/autosome incompatibilities appear to be either absent or to play a minor role in the sterility of male progeny from backcrosses of F-1 males to females from either species. It is suggested that Y/autosome incompatibilities may be among the first to appear in the development of postzygotic isolation in Drosophila. |
