Contrary to popular belief, our features that are transferred genetically are not only those that are physical. Our features that determine our mood also have genetic statements. VMAT2 protein affects tendency to positive thinking via the GOD gene. Similarly, the monoamine oxidase A protein affects mood by being responsible for the destruction of monoamine that is present profusely in amygdala and hippocampus. Kappa opioid receptor, which is more common in females, and Mu opioid receptor, which is more common in males, have determinant effects on substance searching behavior and addiction. Therefore, according to the downregulation/ upregulation mechanism, addiction behavior does not only depend on environmental factors, but also depends on genetic factors.
