Behavioral geneticists work to discover how much of people's behavior is determined by the genetic information they inherited from their parents and how much is caused by their living conditions, learning choices, and other influences from the world around them.

-An inherited trait is a physical characteristic that is passed from parents to their young ones. A behavior is a way of acting. Inherited behaviors are called instincts
