: the study of the relationship between the genetic composition of an organism and its behavior                                      
              
                             The third bridge between the biological and the mental is behavioral genetics, the study of how genes affect behavior.— Steven Pinker,                The Blank Slate,                2003
Steven Pinker,                The Blank Slate,                2003                                        This oversimplified model, which underlies most current research in behavior genetics, ignores the critical importance of the brain, the environment, and gene expression networks.— Dean Hamer,                Science,                4 Oct. 2002
