Figure 2From: Combining identity by descent and association in genetic case-control studiesPower for dominant disease models. Power (y-axis) as a function of the penetrance ratio, γ, (x-axis), for recessive disease model. The allele test, if carried out by itself, is most powerful but, if used in conjunction with the genotype test (MaxGA), is somewhat less powerful than the FP test. All three tests (genotype, FP, MaxGA) have essentially the same power.Back to article page
