The nature versus nurture debate suggests that genetics alone determine a person's behavior and personality, with no influence from environmental factors.

The nature versus nurture debate explores how much our genes and our environment shape who we are. "Nature" refers to the traits we inherit from our parents, like eye color or some aspects of our personality. On the other hand, "nurture" involves our experiences, upbringing, and the culture we grow up in. For example, two siblings may have similar genetic traits but can develop very different personalities based on their different life experiences, like how they are treated by parents or friends. This shows that both nature and nurture play important roles in forming who we become, and it is not just one or the other that influences us.
