Figure 2From: Linkage analysis of alcoholism-related electrophysiological phenotypes: genome scans with microsatellites compared to single-nucleotide polymorphismsAffected-sib-pair linkage analysis with a parent-of-origin model. Linkage results are shown for MS markers (A) and SNPs (B). Solid line indicates the baseline model with ALDX2 as a binary trait, in affected-sib-pairs (ASPs) only. Dashed line indicates the parent-of-origin model, the test for a difference in maternal vs. paternal inheritance. Sample sizes are 321 for MS, 316 for SNP data.Back to article page
