Abstract
We report the first mapping of a genetic factor responsible for reproductive isolation: a small segment of genome strongly affecting sperm motility in hybrids between the sibling species Drosophila simulans and D. mauritiana. Maximum-likelihood analysis of data from ten generations of backcrossing places this factor at 1·1 ±0·2 map units from the forked locus, at position 54·9±0·2 or 57·1±0·2 on the X chromosome.
