QTL results determined by different models for 10thrib backfat (BF10) at 19 and 22 weeks of age on SSC15. Blue and red solid lines indicate BF10 at 19- and 22-wk, respectively, detected with the half-sib model (FDR ≤ 0.005). Blue and red dotted lines indicate BF10 at 19- and 22-wk, respectively, detected with the line-cross model. 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).
