Fig. 2From: Animal models with group-specific additive genetic variances: extending genetic group modelsGenetic group matrix \({\mathbf {Q}}\) (a), and \({\mathbf {T}}_j\) matrices (b, c) for the pedigree example. Group-specific proportions of the genome are stored in the \({\mathbf {Q}}\) matrix. The columns of \({\mathbf {Q}}\) can be used to derive the group-wise matrices \(\mathbf {T_1}\) and \({\mathbf {T}}_2\) by appropriate multiplication with \({\mathbf {T}}\)Back to article page
