It is Difficult to Assign a Precise Phenotypic Definition to Alcoholism

Question

It is difficult to assign a precise phenotypic definition to alcoholism because _____.
A) not enough volunteers agree to participate in genome wide association studies
B) alcoholism does not have environmental components
C) alcoholism is an innate behavior
D) genetic testing for alcoholism is not available
E) excessive consumption of alcohol is subjective

Accepted Answer

Excessive consumption of alcohol is subjective and varies greatly among individuals, making it difficult to assign a precise phenotypic definition to alcoholism. While genetic factors play a role in alcoholism, there are also environmental and behavioral components that can contribute to the development of the disorder. Genetic testing for alcoholism is not widely available or reliable enough to use as a primary method of diagnosis.
