DNA Methylation, Epigenetics, and Evolution in Vertebrates: Facts and Challenges

Figure 3

Plot of 5mC levels against GC levels for the genomes of polar fishes (dark blue circles) and temperate/tropical fishes (light blue triangles). The regression line (broken red line) for the mammalian DNA (data from [49] and unpublished data; see Figure 2) was reported as a reference. Modified from [35].
