Summary
By incorporating ethanol (4% v/v) into the larval rearing medium of a specially constructed Drosophila melanogaster strain it was possible to produce only male adults; the female larvae died.
In this strain, the male determining chromosome was linked with a positive Alcohol dehydrogenase (ADH) allele by a translocation. The females were homozygous for the null allele and hence sensitive to ethanol.
This genetic sexing method is discussed in relation to its use in the genetic control of insects.
