Breed specific additive genetic variance for breed A (\({\sigma }_{a(A)}^{2}\)), B (\({\sigma }_{a(B)}^{2}\)), and C (\({\sigma }_{a(C)}^{2}\)), and local breed proportion variance for breed A (\({\sigma }_{k(AA)}\)) and B (\({\sigma }_{k(BB)}\)), local breed proportion covariance between breed A and B (\({\sigma }_{k(AB)}\)), and residual variance (\({\sigma }_{e}^{2}\)), with standard errors of the estimates
