60IIA>tra^RNAi masculinized females paired with Canton-S females use primarily female aggressive behavior and show male courtship. Fights between a Canton-S female and females of indicated genotypes (experimental flies). Behaviors were scored for 10 min from the first encounter. (A) Number of head butts performed by experimental fly (Kruskal–Wallis test with Dunn's multiple comparison test). Note a much wider variation in the distribution of experimental flies. (B) Number of lunge-like behaviors performed by experimental fly (Kruskal–Wallis test with Dunn's multiple comparison test). Again, note the wider distribution of lunge-like behaviors in experimental flies. (C) Number of lunges performed by experimental fly (Kruskal–Wallis test with Dunn's multiple comparison test). (D) Number of wing extensions performed by experimental fly (Kruskal–Wallis test with Dunn's multiple comparison test). (E) Percent of flies that performed a wing extension before a head butt (wing extension first), a head butt before a wing extension (head butt first), or that showed only head butts and no wing extensions (head butt only). (F) Percent of pairs that began fighting (showing head butts) over a 1-h period. For all histograms, *P<0.05, ***P<0.001, n.s., not significantly different.
