  • The estimated position of the QTL relative to the correct position, when the QTL occurred 100 generations ago, is shown. The effective size of the population was 100, and the residual variance was 1. The number of replicated simulations in which the indicated position was estimated is presented. The total number of replicates is 50.

  • a Measured in no. of marker brackets; i.e., 0 indicates that the estimated position was in the correct marker bracket, 1 indicates that the estimated position was in the bracket next to the correct position, etc.
