Behavioral neurogenetics is a type of science that looks at how genes affect behavior. Genes are the instructions in a person's body that help determine how they look and act. Behavioral neurogenetics looks at how certain genes can influence how a person behaves. For example, certain genes can affect how a person responds to stress, their ability to learn, or even how they interact with other people. By studying how genes influence behavior, scientists can learn more about the brain and how different genes can be used to treat certain disorders or diseases.
