Fig. 2

Comparisons of QTL identified by cim(), QTL.gCIMapping(), and stepwiseqtl() for two differently sized populations. Each figure shows the frequency of QTL identified by 100 iterations. A, B Show simulated QTL (a total of four simulated QTL) identified (LOD > 3.0) for populations of 1000 or 100 F₂ individuals, respectively (e.g., the left panel in A shows all four simulated QTL were identified by cim() in at least 70 iterations, while two out of four simulated QTL were identified in less than 10 iterations). C, D Show potential false positive QTL identified (LOD > 3.0) for populations of 1000 or 100 F₂ individuals, respectively
