Question 2

What are twin studies

Answer 2

• used to investigate the genetic basis of schizophrenia
• identical twins (monozygotic) share a higher percentage of genes than dizygotic so are more likely to suffer from the same psychological illness if the cause is biological

Question 3

What are adaption studies

Answer 3

• also used to demonstrate the genetic basis for schizophrenia. if an adaptated child has schizophrenia and their biological parent also suffers from the illness but their adaptatif parent does not - there is a biological explanation for this

genetic material passed between generation
