Progress in Molecular Genetics and Its Potential Implications in Organizational Behavior Research

Human behavioral traits are heritable. Mainly through studies involving twins, work-related behaviors and experiences have also been found partially influenced by genetic factors. The recent progresses in molecular genetics have provided the opportunity to directly explore the linkage between DNA, the material foundation of heredity, and work-related behaviors. In this chapter, we first introduce some fundamental concepts and methods in molecular genetics. After presenting a model diagram of the unfolding process of genes on work-related outcomes, we explain mechanisms of how gene and environment jointly influence behavioral outcomes. We review recent literature that bridging molecular genetics and psycho-social variables, particularly personality, social attitudes, and cognitive ability, given their vital importance in influencing work-related outcomes. Finally, we outline a few possibilities that the molecular genetics approach can enrich OB research.
