Bivariate density plot of the posterior distribution (1900 samples) of narrow sense heritability \(\left( {h^{2} } \right)\), dominance variance as a proportion of phenotypic variance \(\left( {d^{2} = \sigma_{D}^{2} /\sigma_{P}^{2} } \right)\), and total epistatic variance as a proportion of phenotypic variance \(\left( {i^{2} = \left( {\sigma_{AA}^{2} + \sigma_{AD}^{2} + \sigma_{DD}^{2} } \right)/\sigma_{P}^{2} } \right)\) for the \(A + D + AA + AD + DD\) model
