Document Summary
We also know that females will rematch (vs male strict hierarchies) No, it"s in the nervous system: feminize the male with transformer now males prefer to headbutt instead of lunge, masculinize the female lunge instead of headbutt. It"s not who they fight that matters act the same regardless of opponent. How do you get them to fight instead of courting: mixed behaviours. Feminized males with feminized males can"t figure out if they need to court or fight. Same if you put any of the modified ones with any other class (ex: masculinized females, normal females, normal males) There is a binary between aggression and courtship: we can separate aggression and courtship. You can create a masculinized female who will court like a male but fight like a female. Sexually dimorphic p1 neurons control courtship and behaviour. Sexually dimorphic p1 neurons control courtship and aggression: use optogenetics to activate with light.
