Figure 2From: Substitution rate variation at human CpG sites correlates with non-CpG divergence, methylation level and GC contentCovariation between CpG transition rate and the observed versus expected CpG content (CpG [o/e] ) for intronic regions of the human genome. The three panels show the covariation for datasets A, B and C, respectively. Each grey dot represents one intronic region.Back to article page
