Feminizing OA/TA neurons by expressing transformer (tra) in the Tdc2-Gal4 driven population of neurons, yielded a phenotype in which male flies displayed courtship behavior patterns toward a second male under both aggression and courtship choice assay conditions.
In an effort to only include individuals showing clear interest in reproduction, our sample was further reduced to include only those animals that visited both sizes of the experimental arena and displayed courtship behavior.
