Human behavior genetics is the study of how our genes can influence the way we act and behave. Just like some people are born with certain physical traits, like brown eyes or dark hair, some of us are born with certain traits that impact how we act and make decisions. Our genes can help us understand why someone might be more outgoing or shy, why someone might be more curious or less interested in learning new things, and why someone might be more anxious or risk taking. It's important to keep in mind that genes don't determine our behaviors - it's just one piece of the puzzle that helps us understand our behaviors better.
