From what we have seen available there are two "Body Type" choices - one in the "Origin" tab with Identity, with 2 options and another in the "Appearance" tab with 4 options. I'd say it's pretty likely the first one is a male/female choice and the second is variants on that.
I've seen that as well, but without more corroborating evidence it may just be a redundant option appearing in two different spots.
Like the sex selection we already have in EA currently.
