Fruit flies study magnets homosexual

Provided by The Conversation. The team led by University of Illinois at Chicago researcher David Featherstone has discovered that sexual orientation in fruit flies is controlled by a previously unknown regulator of synapse strength.

As predicted, they were able to turn fly homosexuality on and off, within hours. Necrophilia describes when an animal engages in a sexual act with a dead animal. He optically stimulated neurons in a region of the fruit fly brain known to control courtship decision-making. It has been observed in mammals, birds, reptiles and frogs. The males enter the pride from other prides. By using mutant female flies without eggs and male mutants that lacked key seminal proteins, the researchers also proved that a particular male seminal protein was needed for the oviducts to unloop, allowing the female to ovulate.
