  1. ANOVA were done on BFT standardized residuals with either the allele inherited at IGF2 from the sire (pat) or from the dam (mat); *** p-value < 0.001, ** p-value <0.01, * p-value < 0.05, * p-value < 0.10; in bold are indicated the p-values < 0.10 obtained with the maternal allelic effect model
