Figure 2From: Assessing the power of tag SNPs in the mapping of quantitative trait loci (QTL) with extremal and random samplesThe power using SNPs with an extremal sampling scheme for different population models. The power is obtained using single-SNP and two-locus haplotype data based on 1,000 simulations with a moderate QTL. The bars in each bin and the symbols ("+" and "*") have the same meaning with those in Figure 1.Back to article page
