While it may seem like there is a genetic predisposition for alcohol tolerance, tolerance is not inherited. It results from drinking substantial amounts of alcohol over long periods of time.
How much of alcohol tolerance is genetic?
This evidence was stronger once the researchers removed one family from their analysis whose alcohol tolerance results were thought to be unreliable. The genetic variation that showed the strongest link with alcohol tolerance could only explain 4.6% of the variability in people’s alcohol response questionnaire scores.
Can alcoholism be inherited yes or no?
