Earless people, do exist apparently. I didn't know that either

Yes, there are several difference in the male and female brain. Off the top of my head, males have 7x more grey matter than females, and females have 10x more white matter than males, this leads to several behavioural differences and can be seen in frmi scanners. MTF brains very closely resemble a female brain and vice versa.
I'm not sure if transabled brains and transracial brains are currently being examined in similar ways, but I do look for articles on the topic regularly, it does interest me... to my knowledge, currently, theres no scientific foundation to people identifying this way being based on anything substantial.. yet.. (this might be controversial of me, but i dont think that evidence will ever exist).

Eta. Same goes for earless people trapped in ear-ful bodies... probably
