Fig. 3. Average QTL position MSE as affected by marker spacing. Closed symbols are for no selection (selected fraction of 1) and open symbols are for a selected fraction of 1/16 under the uniRec method. Whiskers give the 95% confidence interval for the average. Figure 3A is for QTL explaining 11.6% of the phenotypic variance; Fig. 3B is for QTL explaining 5% of the phenotypic variance.
