Abstract
An excess of schizophrenia has been observed in the biological relatives of adoptees with schizophrenia. The present analysis examined the possibility that illness observed among 90 half-siblings may have been influenced by assortative mating resulting in excess illness in the biological parents of the half-siblings not biologically related to the adoptees (the coparents). We found no difference in the prevalence of mental illness between 44 index and 26 control coparents.Keywords
