Sex on the brain: 'Doublesex' gene key to determining fruit fly gender
Date:3/21/2010

xpressed in these tissues in both males and females, as they would be key to establishing a normal sexual physiological state.

"Determining gender in a fruit fly seems to be about adding different splashes of ''colour' here or there," he says. "It's not like the canvas, meaning the nervous system, needs to be all blue or pink, just a little bit of blue over here or a little bit of pink over there. Not all cells need to know what sex they are, but those that do need to know will be ones that are important for sex-specific behaviours."

The research performed by Dr Goodwin and colleagues allows greater insight into how a male and female nervous systems may be established and how this may then coordinate the sex-specific physiology needed to create the complete, integrated adult sexual state.
