Figure 1From: Linkage analysis of alcoholism-related electrophysiological phenotypes: genome scans with microsatellites compared to single-nucleotide polymorphismsAffected-relative-pair linkage analysis with P300 amplitude as a covariate. Linkage results (LOD scores plotted over distance in centimorgans (cM)) are shown for MS markers (A) and SNPs (B). Solid line indicates the baseline model with ALDX2 as a binary trait, in only those individuals with P300 data available. Dashed line indicates model with P300 as a covariate. Sample sizes are 204 ARPs for MS, 200 for SNP data.Back to article page
