Figure 4.

Periodicity of CpG sites in the 500-bp region at the 5' portion of the intron. Counts of each distance from 2-50 bp are shown for (a) non-Glires eutherians and (b) Glires species. The 8-bp periodicity is evident only in Glires (p = 2.46 × 10^-3; see Materials and methods), which bears the DMR in this region.
