^^ Interesting theory, Anon. So you're supposing that the Kakuhou is kind of like the Mitochondria?

Ghouls do appear to be a separate species at this point, or at least have enough genetic divergence that reproduction is difficult. (And by this, I mean we've been told that Ghoul/Human fertility is very low to begin with. Then you factor in all the OTHER complications, and half-Ghouls being born is nearly impossible.)
