Power of test statistics F4,a, F3,a, F2,a, and F1,a against the trait allele frequency q1 (A) or marker allele frequency PM1 (B) at a 0.01 significance level for an additive mode of inheritance a = 1.0, d = 0.0, when or q1 = 0.5, respectively. The other parameters are given by h2 = 0.15, , , , i, j = 2, 3, 4, i ≠ j, π12Q = 0.5, δ12Q = 0.25, and sample size n = 40, m = 30, s = 20.
