Fig. 2. Log of the odds (LOD) profiles for associations between molecular markers and disease incidence analyzed using composite interval mapping for (A) field screens (solid line = India/Field-1; dashed line = India/Field-2), (B) glasshouse screens (solid line = India/Ghs, dashed line = UK/Ghs), and (C) average effects across all screens (solid line = predicted means, dashed line = multiple interval mapping). Each graph represents a linkage group. The horizontal line across each graph indicates the level of significance for the presence of a quantitative trait locus estimated from permutation analyses. Note that the y-axis for LG1 is on a different scale to accommodate the high LOD.
