Scientists reverse sex roles in fruit flies
Just one gene can make big difference, study says

Scientists have discovered it is surprisingly easy to reverse sex roles in fruit flies. By changing just one gene, they can make a female perform the courtship ritual of the male.

She'll sing, vibrate her wings and lick a potential female suitor. But it's all for naught, as nature doesn't let the flip-flopped sexual advances proceed to any productive conclusion.

Previous studies found that a single gene controls courtship in fruit flies. Males have a form of the gene that produces a protein, dubbed "fruitless," that governs their complex rituals designed to impress a mate. It also is responsible for the males' preference to breed with females. In females, the gene produces a different form of the fruitless protein.
