The likelihood of a dizygotic twin of a person with schizophrenia also having schizophrenia is about 27%. This is higher than the general population risk of developing schizophrenia, but lower than the risk for monozygotic twins of a person with schizophrenia. This suggests that genetics play a role in the development of schizophrenia, but environmental factors also contribute.
