At birth, genes begin to play a role in the growth of traits that may lead an individual down the path of illegal conduct. A common misconception in criminology is that biology is destiny. Rather, the reality is that the genes that predispose to criminal behavior can be changed through interventions. Interventions can help change one's outlook on life and certain actions, allowing them to see the benefits of choosing right and wrong.
