Table 6 Evidence for QTL significant at the 5% chromosome-wide level for traits related to muscularity and meat quality by chromosome obtained by half-sib analysis. Estimated significance levels (F-value), position, % of F2 variance explained by each QTL, and gene effects.

From: QTL for microstructural and biophysical muscle properties and body composition in pigs
