Figure 2From: Power of association tests in the presence of multiple causal variantsSignificant correlations between SNPs. Significant correlations (r Ï„j > 0.1) between SNPs in (a) the GAW17 data set and (b) a simulated data set in which all SNPs are in linkage equilibrium. On the x-axes is the minor allele frequency at a SNP Ï„. On the y-axes is the number of SNPs j with r Ï„j > 0.1.Back to article page
