Additive and dominance effect give insight in the mode of action of the genes underlying the variance of the traits. Moreover, direction (−/+) of the dominance or additive effects indicates which parent contributes to decrease the trait the phenotypic values in the studied trait. LOD, Log10 of the odd ratio; 95% CI, 95% confidence interval; PVE, percent variance explained; QTL, quantitative trait loci; SE, standard error.
