Figure 2. — Power curves of the test statistics F_4,a, F_4,ad, F_3,a, and F_3,ad, against the disequilibrium coefficient for a dominant mode of inheritance a = d = 1.0 at a 0.05 significance level. F_4,ad and F_4,a are calculated when marker A has four equal frequency alleles; i.e., . The measures of LD are the same as those in Figure 1. F_3,ad and F_3,a are calculated by collapsing two of the four alleles: (A and C) alleles A₁ and A₂ are collapsed as a new one; (B and D) alleles A₁ and A₃ are collapsed to be a new one. The other parameters are q₁ = 0.50, h² = 0.25, N = 200.
