For example, family, twin, and adoption studies1 have convincingly demonstrated that genes contribute to the development of alcohol dependence, with heritability estimates ranging from 50 to 60 percent for both men and women (McGue 1999).
What is the hereditary estimate for addiction to alcohol in both males and females?
The heritability estimates in most studies suggest that genetic variability accounts for 50 to 60 percent of the variation in risk for alcoholism in males. Studies of female twins, in contrast, are less consistent.
What is the estimated heritability of serious alcohol related problems?
Early studies using twin and adoption strategies have found evidence of moderate to strong genetic influences (heritability estimate of 40–60%) on alcoholism among men10–15; although, recent studies do not provide evidence for higher heritability for male early onset alcoholism or for alcoholism with comorbid ASPD16.
Is there a gene for alcoholism?
The “Alcoholic Gene”

What is the heritability of alcoholism?
The heritability of alcohol dependence is estimated to range between 40 and 65%, with no evidence for quantitative or qualitative sex differences in heritability (Kendler et al., 1994; Heath et al., 1997; Prescott and Kendler, 1999; Hansell et al., 2008).
