Quizplus · Accepted Answer

Studies of twins with schizophrenia have consistently shown a higher concordance rate among monozygotic twins (who share 100% of their genes) than among dizygotic twins (who share only 50% of their genes), providing strong support for a genetic component to schizophrenia. Brain deficits and neurotransmitter imbalances, such as the dopamine theory, may also play a role in the development and expression of schizophrenia, but they do not necessarily indicate a genetic cause. The diathesis stress theory suggests that both genetic and environmental factors interact to contribute to the development of schizophrenia.
