Research studies focusing on genetic factors in schizophrenia have found that e.g., paranoid, the other family members inherit a predisposition for that subtype only.

Question

Quizplus · Accepted Answer

Research has shown that an individual with a schizophrenic identical twin has a much higher risk factor (about 50%) for developing schizophrenia compared to the general population.

Answer: B
 Family studies of schizophrenia can help determine the relative impact of genetics and environmental factors in the development of the disorder, allowing the genetic influence to be separated from the environmental impact.

Answer: C
 While genetic factors do play a role in the development of schizophrenia subtypes, it is not necessarily the case that other family members will inherit a predisposition for that particular subtype only.

Answer: D
 This statement is not supported by research. The severity of a parent's schizophrenic disorder does not necessarily impact the likelihood of their children developing the disorder.
