Pedigree and Genetic Groups

Calculates additive and dominance genetic relationship matrices and their inverses, in matrix and tabular-sparse formats. It includes functions for checking and processing pedigree, as well as functions to calculate the matrix of genetic group contributions (Q), and adding those contributions to the genetic merit of animals (Quaas (1988) ). Calculation of Q is computationally extensive. There are computationally optimized functions to calculate Q.
