Not one, but both, of daniel's parents have schizophrenia. what is the approximate lifetime risk that daniel himself will develop the disorder?

It has been said that certain genes often skip a generation. So, if your parents have a particular abnormality a child might not necessarily get the same abnormality. In the case of schizophrenia I cannot imagine that two schizophrenics would even take a chance of having children. Even if they are on medication it does not mean that their life can be even close to normal. After all, they have to take very goodo care of themselves and also their child. Schizophrenia often does not show up until a person hits the approximate age of 20. There is also a factor of something actually triggering the schizophrenia. Going back to my first sentence I can only hope, for Daniel's sake that he does not develop this mental illness.

Ithink it's a, but i might be wrong
