Figure 4.
(a) Plot of LOD scores associated with pyrethroid resistance for chromosomes X, 2 and 3 in the combined maps. Solid lines represent LOD estimated by CIM and dashed lines represent LOD estimated by interval mapping. The straight line along the top of each graph represents the threshold value for LOD calculated according to (van Ooijen, 1999). (b) Plot of LOD scores (CIM) associated with permethrin resistance along the linkage map of chromosome 2 including marker names to orient QTL position. The dashed line across the graph represents the threshold value for LOD.
