Figure 2From: Evolution of conserved secondary structures and their function in transcriptional regulation networksDAFs are lower for SNPs in CSSs than in flanking sequences. Derived allele frequencies (DAFs) were calculated in bin frequencies of width 0.1 for four HapMap populations: A: CEU; B: YRI; C: JPT; D: CHB. Black bars represent data for SNPs in CSSs and gray bars indicate their flanking sequences.Back to article page
