Question

Quizplus · Accepted Answer

Saying that schizophrenia is heritable means that there is a genetic component to the disorder and that individuals with close blood relatives with schizophrenia are more likely to develop symptoms than those without such relatives. It does not mean that everyone who inherits the gene(s) for schizophrenia will always present symptoms, nor does it provide an immunity to the disorder. The prevalence of schizophrenia in the population is also not related to heritability.
