Figure 1. The distribution of CpGs. (A) The global distribution of CpGs and dynamic CpGs. From outside to inside, density plot show the global DMCpGs between tissues, dynamic CpGs with age (muscle and testis), and DMCpGs between breeds. (B) The intergenic and intragenic CpGs. (C) Positions of CpGs relative to CGI. (D) The distribution of CpG methylation levels. (E) Mean global methylation level of 20 samples. (F) The distribution of methylation levels in different genome regions.
