According to the biological view of etiology, what is different in children of alcohol-dependent parents?

The biological view of etiology emphasizes the role of genetics in the development of substance use disorders. Research suggests that children of alcohol-dependent parents are more likely to inherit certain genetic predispositions that make them more susceptible to alcohol and drug dependence themselves. These genetic factors can influence how individuals metabolize alcohol, how their brains respond to it, and their overall vulnerability to developing substance-related problems.

While the environment and upbringing certainly play significant roles in a child's development and risk for addiction, the biological perspective focuses specifically on inherited traits and vulnerabilities that are passed from parents to children. This genetic predisposition can manifest in various ways, such as an increased risk for developing addictive behaviors or difficulties in regulating emotions and impulses.

Other options, while relevant, do not align with the biological viewpoint. Environmental and upbringing factors are more closely related to social or psychological models of addiction. Likewise, likelihood of forming friendships and access to treatment methods are influenced by external factors rather than biological ones.
