Studies of the species barrier between Drosophila subobscura and D. madeirensis. I. The genetics of male hybrid sterility.

Heredity - 1 Oct 1991

Khadem M, Krimbas C B

Abstract excerpt

The genetics of hybrid male sterility between Drosophila subobscura and D. madeirensis were studied with the help of 20 markers in backcross males. A major effect resides in the sex chromosomes: backcross males with the X and Y of different origin (mad X-sub Y or sub X-mad Y) have very small and empty testes. In compatible combinations testes are of normal size but males may be sterile or fertile depending on the...
