While Diem is pregnant,she worries that her children are also going to suffer from schizophrenia.Trying to calm her down you present her with research that suggests that _______________.

A) because they are twins at least one of them will not have the disorder
B) if they diagnose the disorder early they can completely cure it
C) schizophrenia has a very weak genetic link
D) they will not inherit the disorder, but only a vulnerability to it

Research suggests that schizophrenia has a strong genetic component, but it does not guarantee that a person will develop the disorder. Twins have a higher chance of developing schizophrenia if one of them already has the disorder. However, they will not necessarily be affected at the same time, and it is possible that one twin will develop schizophrenia while the other twin will not. Therefore, it is likely that both Wes and Cam inherited a vulnerability to schizophrenia from their mother, but only Wes developed the disorder.
