So the dancestors are both love AND hate babies at the same time?

I mean, yes, most likely outcomes is that the Love and Hate genetic material of every Prospit Troll was dumped into the same vat, and then mixed to produce 6 different variables, then repeated for the Derse Trolls. No neat ‘Karkat + Terezi = Latula’ mixes or anything like that, just, true to life Troll Genetic Slurry.
