The selection test for the ADH1B gene region. (A) The haplotype-bifurcation diagrams for the core haplotype with at least 9% frequency at the ADH1B gene region in the East Asian populations. The core haplotype CTTCG shows unusual long-range homozygosity. (B) The EHH and REHH plots of the core haplotype covering the candidate SNP (rs1229984) in the East Asian populations. The EHH and REHH values are plotted against the physical distances extending both upstream and downstream of the selected core region. Only the core haplotypes with frequency ≥9% are shown.
