It`s very hard to tell how much of a risk of Schizophrenia comes from being raised in a schizophrenic family and how much of the risk was inherited by nature of being born into a schizophrenic family, and how much the two interact. The result is that genetic dispositions are generally underestimated (on the side of statistical caution) -- which is probably a good thing anyway. -- Craig Werner !philabs!aecom!werner What do you expect?
