If a mom has schizophrenia, how much percentage chance does her normal daughter have, of getting a schizophrenic child?

Pretty good data. Check out this summary site: http://www. Schizophrenia. Com/research/hereditygen. Htm available data suggest about a 5% risk, compared to 1% in the general population. That's a 5-fold increase in risk, but it's still pretty low, overall.
