Figure 3. Multipoint variance-components linkage LOD scores for OOA (left) and ASHK (right) for two different SNP densities. ALL SNPs analyses used all markers that passed quality control measures (1,236 for OOA and 1,227 for ASHK); 198 SNPs analyses used a subset of 198 markers spaced at least 100 Kb apart (mean inter-marker distance = 133 Kb). Locations of linkage peaks using ALL SNPs are indicated by vertical lines.
