Fig. 2From: Comparison of host genetic factors influencing pig response to infection with two North American isolates of porcine reproductive and respiratory syndrome virusHeat Map of genetic correlations between viremia and weight gain during the course of infection with the a NVSL or b KS06 PRRSV isolate. Genetic correlations from fitting a bivariate animal model in ASReml [28] using the full G-matrix. NVSL and KS06 were analyzed separately. All trials, except trial 13, were used in the analysis. Each square in the heat map represents the genetic correlation between viremia at a given time point t (X axis) and the 3-day weight gain at time point t* (Y axis)Back to article page
