Figure 2.

Effect of additional markers and animals on statistical power for QTL detection. Blue lines indicate last rib fat (LRF) QTL at 19-wk and red lines indicate 10th rib backfat (BF10) QTL at 19-wk on SSC6. Solid lines are second scan results and dotted lines are first scan results. 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).
