we use a variance component model to handle familial relationships.In a sample of n individuals, we model the observed phenotype vector (y) as a sum of covariate effects (specified by a design matrix X and a vector of covariate effects '''β'''), additive genetic effects (modeled in vector g) and non-shared environmental effects (modeled in vector ε). Thus:
