Figure 3.

QTL results determined by different models for longissimus muscle area (LMA) at 19 weeks of age on SSC7. Blue and red lines indicate LMA QTL at 19-wk detected by line-cross and half-sib models, respectively (FDR ≤ 0.002). Marker positions are shown as triangles on the X-axis (gray, markers used for both QTL scans and genotyped only in 510 animals; green, markers used for both QTL scans and genotyped in all animals; red, markers used for second scan only and genotyped in all animals). Horizontal lines indicate significance thresholds (lower line, 5% FDR; upper line, 1% FDR).
