What is the evidence for and against genetics in alcoholism?

What will be an ideal response?

Having one or two parents with alcoholism increases the risk of a child also having it. Adopted children whose biological parent had alcoholism had higher risk than if their biological parent did not have alcoholism, even if their adoptive parent did. Differences have been found in pre-alcoholic men - men with alcoholic parents who are not yet alcoholic - such as different physiological reactions to alcohol and greater conditioned response to alcohol cues. Certain ethnic groups have abnormal physiological reactions to alcohol that seem to make them more or less likely to develop alcoholism. However, genetics cannot fully explain the patterns and changes in alcoholism. Most children of alcoholics do not become alcoholic, regardless of whether they were raised by their parents. Some studies have found no differences in the children of alcoholics and the children of non-alcoholics. GRADING RUBRIC: 10 points, 5 for evidence for and 5 against.
