Table 3 Direct and social genetic variances for average daily gain (g/day) on the diagonal, genetic covariances below the diagonal, and genetic correlations above the diagonal from matrix \({\text{G}}_{{\text{L}}}\) in Model 2 for Landrace (\({\text{L}}\)) and the \({\text{L}}\) dam component in the crossbreds (\({\text{YL}}\))
From: Selection for social genetic effects in purebreds increases growth in crossbreds
