Figure 1. .
Results of stratified linkage analysis. In each plot, the solid line represents the results from the original (full sample) linkage analysis, plotted as the −log(P value) versus the distance from the first marker. The dashed line represents the results from S1. The dotted line represents the results from S2. The horizontal lines represent P values of 1.0×10-3 (lower) and 2.2×10-5 (upper). The values to the right of the plots represent the corresponding LOD scores.
