  1. The stepwise model selection method resulted in a multi-QTL additive model for each trait. The rows describing individual QTL contain position information, mean phenotypes for each genotype class at the QTL position, and LOD and PVE values that compare the full model to a sub-model with the individual QTL term dropped. Rows labeled “Full model” show the LOD and PVE scores for the additive model that includes all of the QTL terms. Genotype classes are labeled according to the grandparent of origin of each allele. Phenotype values are residuals to standard length in millimeters
