  1. 1The population structure was a mixture of full and half sib families for given numbers of sires (s), dams per sire (d), and progeny per dam (p).
  2. 2Significance level for the LRT.
  3. 3Power of the QTL detection at significance level α.
  4. 4RMSE of the estimated QTL location, the true QTL being located at 0.1 M on a 0.4 M linkage group.
  5. 5Proportion of QTL located at a marker location (3 markers at 0 M, 0.2 M and 0.4 M).
