2 The thresholds of LOD for CW, CSW, CSR, and PW were 2.67, 2.69, 2.54, and 2.78, respectively.
3 The statistical power represents the detected number of LOD values that were > 2 in 100 random replicates by multi-marker joint analysis.
4 Q3-1 possesses an extremely similar LOD value (LOD = 3.02) for PW to Q3-2. In addition, their similar effects (r2 of 13.95 and 13.94%) and close positions (2 cM) indicate that they may share the same region.
