Which statement best reflects the heritability of schizophrenia

Question

Quizplus · Accepted Answer

The heritability of schizophrenia is complex and not fully understood, but research suggests that genetics does play a role in the development of the disorder. Studies of families, twins, and adoption all suggest that some people inherit a genetic vulnerability to schizophrenia. However, it is not a simple case of one gene causing the disorder and the inheritance pattern is not just a matter of dominant or recessive genes. Concordance rates for identical twins (who share all their genes) are higher than for fraternal twins (who share about 50 percent of their genes), but it is not near 100 percent, indicating that environmental factors also contribute.
