  1. *: significant at the 5% chromosome-wide level, **: significant at the 1% chromosome-wide level, ***: significant at the 5% genome-wide level
  2. 1the fraction of phenotypic variance in the F2 explained by a QTL; calculated as the proportion of residual variance of the statistical models with and without the QTL effect
  3. 2positive values of additive genetic and dominance effects imply higher trait values forced by the Duroc allele;
