but considering that kaneki is a human turned ghoul, do you think that his genes have been modified as well or do they remain mainly as human? is there a possibility that, even if his genes were mixed, touka's body might absorb the baby due to it's part human genetics? since in the end, kaneki's meat still tastes good and is able to provide ghouls with sustinence as well?
Oh yeah, I forgot what Itori said about the dangers of a Ghoul mother to a Half-Ghoul child. Kaneki’s genes are definitely mixed - he only had a kakuhou implanted within him, but his skin became impervious to human weapons, he gained regenerative abilities and most telling of all, his sense of taste changed, and now only human meat can sustain him.
But there’s no reason Kaneki should have that enzyme, and his tongue is the same as the one he’s always had…in theory.
But my theory is that the kakuhou pumps out enormous quantities of RC cells which alters the biology of the Human towards more Ghoulish standards, albeit incompletely (represented by Kaneki’s half-kakugan, and the fact his meat is still tasty despite having Ghoul levels of toughness). So yeah, Kaneki’s genetic sequence has been altered by the kakuhou inside of him. The same incomplete process is true in naturally-occurring Half-Ghouls as well, with varying rates of Ghoulification - Rize having two kakugan and Arima having none, for example. I would also conjecture that the reason Half-Ghouls are rumoured to be stronger than regular Ghouls is because the kakuhou produces more RC cells in reaction to the human body initially rejecting them, battering human natural defences until they give in and become Ghoulish.
Because Kaneki is still quite delicious there is a high chance that a Touken baby would be absorbed by Touka in the womb. But it’s still not definite - it’s kind of a gamble really, depending on what traits it gains from its mother and what traits it gains from its father.
