>>43329859Gretchin, if I remember this correctly, are made to be scrawny, weak, and submissive. The only way that this would happen is if something went wrong in their genetic code. And since I'm pretty sure Gretchin don't live for very long, I think without any orks to help them move along, the settlement would die, even though more Gretchin and orks would still be made.
Still, it's a concept that was messed around with by some guy who made the Red Starz. Pretty cool, if you ask me.
