For each trait the linkage group, position on genetic map and nearest genetic marker on genetic map, LOD scores, means of the three genotype classes (μ_A, μ_H and μ_B), percentage of variation explained and additive and dominance effects with standard errors have been given. The additive and dominance effects and standard errors come from the analysis of the log-transformed data, but the genotype means have been back-transformed to the natural scale
