Genetic Influence on Cognition and Behavior
A researcher observes that identical twins, who share the exact same genetic makeup, are separated at birth and raised in different families. As adults, they both exhibit a similar predisposition to anxiety, despite having vastly different life experiences and upbringings. Which principle does this observation most strongly support regarding the biological foundations of behavior?

Genetic Links to Behavioral and Psychological Traits
A researcher identifies a specific gene variant strongly associated with a predisposition for high-risk behaviors. Two identical twins, both possessing this gene variant, are adopted into different families. Twin A is raised in a stable, supportive environment with clear boundaries and guidance. Twin B is raised in a chaotic, unsupervised environment. Based on the principles of how genetic blueprints influence psychological traits, which of the following is the most likely outcome?
