Relationships between overall performance (${\mathbf{a}}_0$ and $\mathbf{O}\mathbf{P}$) and stability (${\mathbf{a}}_1$, ${\mathbf{a}}_1^{\ast }$, $\mathbf{S}$ and $\mathbf{R}2$) within the RN and FA models. The correlations are printed in each frame. RN-L: linear reaction norm; RN-NL: nonlinear reaction norm; FA-2: factor-analytic model with two common factors and specific genetic effects; RR-2: reduced-rank factor-analytic model with two common factors and zero specific genetic effects
