- LIKE BROTHER, LIKE SISTER
-
- Conventional medical wisdom holds that men are driven to
- alcoholism primarily by their genes, women by their social
- environment. Not so, according to a report in the Journal of the
- American Medical Association by a team led by researchers at the
- Medical College of Virginia. Interviewing 1,030 sets of female
- twins, they found that when one sister was alcoholic, odds that
- the other would have a drinking problem were greater among
- identical vs. fraternal siblings. Heredity accounts for 50% to
- 60% of a woman's vulnerability to alcoholism, about the same as
- for men.
