A mutation which changes courtship song in Drosophila melanogaster.

A mutant Drosophila melanogaster with an aberrant courtship song has been isolated. The interval between pulses and the length of the pulses are increased. The pulses are polycyclic rather than monocyclic. Flight wingbeat and sine song frequency remain unchanged. The mutation is mapped and fate-mapped. The results from the latter investigation are inconclusive.
