Wow - I didn't know chromosomally gender could appear on a spectrum. How many chromosomes can determine gender and how many gradiants are there on a genetic scale? It totally makes sense having heard that, and you get a feel with some people that their gender is a mismatch, and that feeling goes on a scale too.
I'm thinking particularly of a woman I worked with we are pretty sure she had misplaced gender. She is pretty as a woman, but has some masculine features and moves like a man. It's strange and hard to explain, but with some people you just know, do you know what I mean? Well, this woman was from a very religious family and wouldn't dream of exploring anything outside set expectations. She has a serious boyfriend now, and I feel a little sorry for her, but at the same time what do I know?
