Final answer:
Genetics and environment both influence personality traits.
Explanation:
False
Many psychologists believe that characteristics such as intelligence, emotion, and personality are influenced by a combination of genetics and environmental factors. While genetics play a significant role, nonshared environmental influences, such as upbringing and interactions among genes, also shape these traits.
