A gene known as doublesex is responsible for the differences in anatomy and behaviour of males and females in many animal species. The male doublesex gene is active in around 650 neurons - specialised cells that transmit nerve impulses - with specific groups of cells controlling distinct steps in the courtship ritual. However, it was not known how these different steps are coordinated to ensure successful mating.
