Power and type I error for single-locus and region-based QTL mappings. Power and type I error for three region-based QTL mappings: (A) combined analysis; (B) rare-variant-only analysis; and (C) common-SNP-only analysis. In each panel, the results of the single-locus QTL mapping are also provided for comparison. Red bars indicate that a QTL is identified by both single-locus and region-based QTL mappings. Blue hatched bars indicate that a QTL is identified only by the single-locus but not the region-based QTL mapping. Green hatched bars indicate that a QTL is identified only by the region-based but not the single-locus QTL mapping.
