Explanation:

Behavior is influenced by multiple factors including genes and environment. Just having a single gene associated with aggressive tendencies does not guarantee aggressive behavior. There is no certainty that either twin will show aggression due to the complexity of gene - environment interactions.

Answer:

B. It is unlikely that either will show aggressive tendencies.
