Abstract excerpt
Male sexual behavior is regulated by the sex-determination hierarchy (SDH) in Drosophila melanogaster. The fruitless (fru) gene, one of the regulatory factors functioning downstream of other SDH factors, plays a prominent role in male sexual behavior. Here we demonstrate that fru mutations cause a previously unappreciated behavioral anomaly: high levels of head-to-head interactions between mutant males. These...
