^aIMQP indicates all animals of the Illinois Meat Quality Pedigree analyzed in this study.

^bShear and Tender denote Instron Shear Force and Taste Panel Tenderness, respectively.

^cValues significant at the p = 0.05 and p = 0.01 levels, as determined by chromosome-wise permutation (n = 5,000), are indicated with one and two asterisks, respectively.

^dDenotes standard error associated with additive effects.

^eDenotes standard error associated with dominance effects.

^fConfidence interval as determined by bootstrapping (n = 1,000).

^gIncludes CAST as a fixed genetic effect.
