If a person inherits genes that predisposes him or her to alcoholism but is raised in saudi arabia, how is that person likely to behave in terms of alcohol consumption?

Genetic predisposition is a characteristic that makes certain people more susceptible to a particular disorder or condition.  

However, the impact of this characteristic can be managed through lifestyle choices. If a person with a genetic predisposition to alcoholism is raised in Saudi Arabia (in a culture where he has no access to alcohol) he would have no trigger, and this disorder would not become present.
