ALCOHOL ADDICTION AND GENETICS
Our genetic structure determines all our human traits. Our DNA dictates our physical characteristics (such as eye color) and also our behavioral characteristics (such as aggression). These genes are passed on to us by our parents.
Among the behavioraltraits parents can pass on to their children is a predisposition toward alcohol abuse and addiction.
Among those abusing alcohol, people who are genetically predisposed to alcoholism have a higher risk of becoming addicted. Although people can inherit alcoholic tendencies, the development of an alcohol use disorder is also dependent on social factors. Some who have inherited genes making them susceptible to alcoholism are responsible drinkers or never take a drink in their life.
