Table 1 presents ADH1B and ADH1C genotype frequencies for the full sample. Thirty-four percent of the sample had at least one ADH1B*3 allele, while 25% had at least one ADH1C*2 allele. Hardy-Weinberg equilibrium was not significant for ADH1B (rs2066702; χ2 (1, N = 116) = 0.39, ns; rs1229984; χ2 (1, N = 116) = 0.02, ns) or ADH1C, χ2 (1, N = 116) = 0.07, ns; Rodriguez, Gaunt & Day, 2009). Chi-square analyses did not indicate a significant association between ADH1B and ADH1C genotype frequencies (χ2 (6, N = 116) = 7.27, p = .30). The distribution of genotypes did not differ across gender or ethnic group (African American, mixed race, Hispanic/Latino).
