Abstract

Hybrids obtained in the laboratory between two subspecies of Drosophila paulistorum possess a genetic constitution which is discordant enough so that the hybrid females repel the courtship of all males, and will mate with none. The hybrid males will court and will be rejected by almost all females, including their own hybrid siblings.
