Variance decompositions for second hypothetical gene-environment interaction model for P moderated by M, presented in § 4.3. Left: Incorrect variance decomposition according to formula (12). Center: Correct variance decomposition for unique effects g2 and g3 controlling M. Right: Correct variance decomposition for environmental effects h2 controlling genetic effects.
Note: For center panel, effect variance due jointly to AM and EM combined is 0.92 and is not shown in the plot because it is not a function of M. For right panel, effect variance due to all genetic effects AM and AU is 1.05 and is not shown in the plot because it is not a function of AM or AU.
