The genetics of alcohol consumption in animals |
| |
Abstract: | Abstract This paper reviews animal studies of genetic differences in the consumption of alcohol. It deals with six areas: (1) field observations in nature; (2) selective breeding; (3) variation among inbred strains; (4) correlates of ethanol preference and avoidance; (5) consumption and sensitivity; and (6) a test of an ethanol intake control system. Because of space constraints it is selective rather than exhaustive. The results of experiments demonstrate that genes have a strong effect on alcohol consumption when animals are given a choice of liquids. Both preabsorptive and postabsorptive factors can modify intake. There are similarities in factors that affect alcohol consumption in animals and those believed to be operative in humans. Evidence for an ethanol intake control system is presented. |
