Studies have shown that schizophrenia has a heritable component.

Numerous studies have suggested that schizophrenia has a significant genetic component. The risk of developing schizophrenia is higher for individuals who have a family history of the disorder. Twin studies have also shown that there is a higher concordance rate for schizophrenia among identical twins compared to non-identical twins. However, it is important to note that genetics is not the only factor involved in the development of schizophrenia, and environmental factors play a significant role as well.
