^ There´s a parasite in real life called "Toxiplasma Gondii" that can infect humans... and can also be passed on from mother to child, which is the only real dangerous thing about this parasite when it comes to human infection since its natural hosts are cats. A human is a dead end for them.

Yes, you can, if you´re unlucky, inherit toxiplasma gondii from your mother and get "Toxiplasmosis" before you´re even born, if you´re lucky, you live, but you´re stuck with the parasite for the rest of your life and if you´re a woman... well, it passes on to the next generation from there.

...

One-eyed ghouls are also easy to explain...

People that can turn into these, are rare, that has been proven by Kanou´s experiments. The reason kaneki Ken and Seidou and the Twins survived, is because they got the genetic code of a higher developed immunesystem that seperated them from others from the day they were born. Genetic mutations at the most basic level.

They are the same as the very first people who had the genetic code to endure the rc-cell infection from the dawn of the Ghouls, which spread these genes through selective evolution.

The artificial one-eyed ghouls are made from those with the same genetic codes and potential.

The Quinx are also the of the same category, I believe that they would have become one-eyed ghouls if they just had the kakuhou colony put in them without frames and survive even without frames to keep the infection in check which kept them "somewhat" human instead.

Only four out of hundreds had the potential to have a kakuhou in them and survive (Original quinx.)

It´s all about genetics.
