- n. A gene that is involved in the sex determination system of the fruit fly Drosophila melanogaster, expressed in both male and female flies.
The fruit fly gene "doublesex" is responsible for ensuring that male flies look male and females look female.
New Brown University research led by biologist Michael McKeown shows that doublesex not only helps shape bodies but also shapes behavior, acting with together with the gene "fruitless" to guide flies 'courtship routines and responses.
