Fig. 2From: Genotype-by-environment interactions for reproduction, body composition, and growth traits in maternal-line pigs based on single-step genomic reaction normsHeritability estimates using reaction norm models with homogenous (RNM1) and heterogeneous (RNM2) residual variances. Respective optimal RNM for each trait are marked by the solid lines; TNB: total number of piglets born; NBA: number of piglets born alive; WW: weaning weight (kg)Back to article page
