$λ_{X} = σ_{X}^{2} / σ^{2}$ : variance ratio. $h_{X}^{2} = σ_{X}^{2} / σ_{P}^{2}$ : proportion of phenotypic variance contributed by each type of variance. H: the broad sense heritability defined by $H = σ_{G}^{2} / σ_{P}^{2} = (σ_{P}^{2} - σ^{2}) / σ_{P}^{2}$ . $e^{2}$ : the proportion of the environmental contribution defined by $e^{2} = σ^{2} / σ_{P}^{2} = 1 - H$ .
