| Research Abstract |
Using the classical twin approach, wherein correlations between monozygotic twins and those between dizygotic twins are compared ; we explore to what extent genetic factors account for interpersonal variation in preference parameters. We find that substantial parts of the variations are explained by both genetic factors and common environmental factors : For immediate future choice, 24% of the variation can be accounted for by additive genetic factors and 26% by common environmental factors ; for distant future choice, 23% and 22% of the variation can be accounted for by additive genetic factors and common environmental factors, respectively.
