Yet another way of looking at this

Gender is a word for all the psychological, social and behavioural aspects that a culture associates with being male or female.
Western culture is strongly binary and groups gender - as defined above - into either masculine or feminine, meaning trait 'choices' are either/or situation depending on sex assigned at birth. There's no evidence which suggests this is anything but a convention society has settled on, but it's stable purely because most children don't get to make trait choices, they are imposed on them by their parents, wider family and social group.
If western culture was different, then all people, regardless of sex assigned at birth, might now be being brought up with what we regard as masculine traits, or conversely everyone might be being taught feminine traits, or there might even be no preference one way or another with children allowed to develop their own collection of traits.
Even the traits themselves are up for grabs, because they too are culturally defined, that's the shocker. There's no reason why another society couldn't decide to add traits, swap them around between genders, or add in extra genders. The latter already happens with third gender people in India and Pakistan, and two spirit native Americans; while the former can be seen in some Polynesian societies, and probably others, I just can't think of any at the moment because I'm hoping Lilis's date is going okay.
Which isn't to say society's conventions are right. Is this any closer to answering your question about what contributes to gender? Effectively, what I'm trying to say is that gender (again as defined above) is something society arrived at by accident over a few thousand years.
