Note: Proportions of the variance in each phenotype due to additive genetic influence (A), dominance influence (D), common or shared environment (C), and unshared or unique environment (E). Ninety-five percent confidence intervals are in parentheses. Estimates from family data use four-member families, whereas estimates from twin data are based only on the twins. Results of family models are for ACE and ADCE. Twin data can only be used to estimate ADE or ACE models; C and D cannot be estimated simultaneously in the same model.
