The inheritance of sz

It is known that schizophrenia has a heavy genetic component. But also many of us with sz never have children. So how do you explain that the disease persists through generations at such a high rate? I seems that the disease would be selected against.

Maybe it’s not genetic. Nobody has a clue what causes it.


Darn good point my friend, darn good point.

Sometimes it pops up in a family without it. Maybe after it pops up, from that point on it’s carried in the genes? I’m not sure. But like I said it’s a good point and I’m surprised I never thought of it.

Maybe because if someone with sz had a sibling that doesn’t have sz, and they have kids the gene is still passed onto the kids? Only thing I could think of.
