σAO2 = additive direct genetic variance, σDO2 = dominance direct genetic variance, σAOAM = direct-maternal additive genetic covariance, σAM2 = additive maternal (or 'indirect') genetic variance, σ2DM+C = dominance maternal genetic variance and common environmental variance (maternal and cage), and σE2 = residual environmental variance. Asterisks denote statistical significance (* p < 0.05) | |||
