Yes, I know this is a politically charged topic these days; and seeing how I don't intend for it to be a HUGE plot point (in the sense that this isn't a political piece), I questioned even making this thread at all. Especially considering that researching it online gives me all kinds of social justice nonsense. But I want to be as accurate and realistic as I can. I have in mind a character who was genetically engineered to be (among other things) as gender neutral as possible, a well as raised to have no significant gender identity. What I need to research is what genetic possibilities there are for humans - typical karyotypes with hormonal or neurological abnormalities doesn't quite cut it for me. What I'm trying to find is what sequence could produce the most gender-neutral/gender mixed body. The mental stuff is a bit easier to read about and explore, so I'm focusing on biology here. I imagine that since there's deliberate genetic tampering going on, I might have a little more freedom for strange-but-still-human biology. Essentially, is anyone knowledgeable about human genetics enough to figure this out, or does anyone have some (apolitical) resources about unusual sex expression? In addition, what's the best way to refer to a genderless character? I've been using the singular they in drafts and sketches, since it seems most normal and subtle, but is that sufficient?
