F -statistic profiles for carcass or body weight (Sire C only) on BTA 6. Marker locations were obtained from the Shirakawa-USDA linkage map . Bold and thin lines indicate a fixed-effect QTL model and a fixed-effect QTL model accounting for the effect of SNP-9 of NCAPG, respectively. The boxes on the x-axis indicate the 95% CI of the QTL. The horizontal lines indicate the thresholds for chromosome-wise 0.1% (- - -), 1% (- -), and 5% (---) significance levels.
