Note: LG, linkage group; A, additive QTL effect; D, dominance QTL effect; SI, 2-LOD support interval in the fit; R2, percentage of phenotypic variance explained by the QTLs. Only QTLs above empirical threshold of 3.0 are listed (LOD threshold computed by 1,000 permutations). The positive and negative effects indicate that the allele which increases the trait values is in the paternal and maternal parent, respectively.
