From Nature:
Catherine Dulac and her colleagues at Harvard University genetically engineered female mice to lack a gene called TRPC2. This gene is essential for the functioning of a pheromone-sensing organ in the nose called the vomeronasal organ.
Without the gene, female mice acted exactly like males - even towards male mice - complete with mounting, pelvic thrusts and the ultrasound calls that males use to attract a mate.
