The consequences of incorrectly specifying the covariance matrix of BV is discussed. The theory of the covariance between relatives in crosses from 2 populations is extended for predicting BV in models with multiple traits. A numerical example illustrates the prediction procedures. cross heterogeneous additive variance segregation variance genetic group BLUP-animal model Resume Prediction des valeurs génétiques avec des modèles individuels additifs pour des croisements à partir de 2 populations. De récentes avancées de la théorie de la covariance entre apparentés dans les croisements entre 2 populations en hérédité additive sont utilisées pour prédire les valeurs génétiques VG par le BLUP-modèle animal. Les consequences resultant d une definition incorrecte de la matrice de covariance des VG sont discutées. La théorie de la covariance entre apparentés en croisement à partir de 2 populations est étendue à la prediction de VG pour plusieurs caractères. Un exemple numérique illustre les procedures de prediction. croisement BLUP-modèle animal variance génétique additive hétérogène variance de segregation groupe génétique 324 RJC Cantet RL Fernando INTRODUCTION A common method used to genetically improve a local population is by planned migration of genes from a superior one. For example in .
