Genetic evidence regarding twins and the risk for schizophrenia supports which fact?

Question

Quizplus · Accepted Answer

Genetic evidence shows that monozygotic twins (who share 100% of their DNA) are significantly more likely than the general population to both have schizophrenia. This suggests a strong genetic component to the disorder. Concordancy rates are much lower in fraternal twins (who share only 50% of their DNA on average), indicating that genetic factors are a major contributor to the risk of developing schizophrenia.
