The likelihood of a monozygotic (identical) twin of a person with schizophrenia also having schizophrenia is about 50%. This is much higher than the likelihood for dizygotic (fraternal) twins or other siblings of a person with schizophrenia. This high concordance rate suggests a strong genetic component to schizophrenia, although environmental factors also play a role.
