Sex is complex — but then again, there are a lot of other factors at play and, clearly, environment can have a big influence on how sex expresses itself.

The sex chromosome effect therefore occurs robustly under distinctly different hormonal conditions. I agree with the gender as social construct thing. Stop trying to give excuses for people to identify in different ways because it makes them feel better. More generally, any genetic variation among X alleles, even those not causing overt disease e.
