So, I’ve watched all of Stargate SG-1, and I’m confused about the sexuality of the Goa’uld (and Tok’ra, which I’m just going to call Goa’uld because it’s easier). How do they reproduce? Do they have genders? If they do have genders, how are they distinguished? This confusion is worsened oleh exposition that seems to change the nature of the Goa’uld physiology over the course of the show, retroactive continuity change that isn’t clearly resolved, specifically in regard to the Goa’uld queens.
