Gene-Environment Interaction in Behavior

In the field of psychology, the interaction between genetics and behavior is a crucial area of study. One prominent theoritical framework posits that the influence of genetic predispositions on behavior can be moderated by environmental factors. Recent studies in behavioral genetics have discovered the importance of specific genes in the expression of traits and behaviors. This relationship underscores the complex interplay between heredity and environment.

Consider the following scenario: A set of identical twins, raised apart in different environments, showcases significant differences in their personalities and interests. Researchers suggest that these differences can be attributed to the variance in their non-shared environments as well as the identical genetic makeup they share. Based on this information, which of the following statements best exemplifies the principle of gene-environment interaction?
