genetics

• The genetic explanation suggests that there is a gene that can be inherited that predisposes the individual to develop schizophrenia
• family studies, twin studies, adoption studies all suggest genetics play a role in the development of schiz
• genetics cannot be the sole factor since concordance rates for schiz in MZ twins hardly match their 100% genetic similarity
• genetic explanations do not account for the cases of schiz which appear in families with no history of the disorder. environmental factors must also play an important role
