Direct-effect QTLs are listed by phenotype affected, name, chromosome, location from centromere in centiMorgans and Confidence Interval of 1 LOD (CI), Standardized additive effect, 2a/σp, and Standardized dominant effect, d/σp (with asterisks indicating significance), and percentage of variation explained. Genome-wide threshold is 3.27.
