Which statement BEST reflects the findings of twin studies evaluating genetic factors associated with schizophrenia?

A) If one twin has schizophrenia, the other twin-if male-has a significantly increased risk of developing schizophrenia.
B) Identical twins are almost five times as likely to develop schizophrenia as are fraternal twins.
C) If one twin has schizophrenia, there is a significantly increased risk of schizophrenia developing in the other twin, for both identical and fraternal twins.
D) If one twin has schizophrenia, there is an increased risk of schizophrenia developing in the other twin, with a substantially higher risk for identical twins.

Genetic Factors

Elements within an organism’s genes that can influence physical traits, behavior, and susceptibility to certain conditions.

Identical Twins

Twins that result from the splitting of a single fertilized egg, sharing the same genetic makeup.

Fraternal Twins

Twins that develop from two different eggs fertilized by two different sperm, making them genetically as similar as regular siblings.
