Using Extended Genealogy to Estimate Components of Heritability for 23 Quantitative and Dichotomous Traits

Figure 1

Average heritability estimates and 95% confidence intervals of 17 phenotypes for six classes of relationship.

The differences in heritability estimate between classes of relationship are consistent with a shared-environment only effect on phenotypic correlation, but not with a dominance only or epistasis only effect on phenotypic correlation.
