The trend in CGI distribution in different functional elements. a, J07. b, J08. c, J09. d, J10. e, J11. f, J12. HP (J07, J08, J09), High Prolificacy. LP (J10, J11, J12), Low Prolificacy. H = A, C or T. The abscissa represents the different regions of gene functional elements that a, b, c, d, e, f, g denote upstream, first exon, first intron, inner exon, inner intron, last exon and downstream, respectively. The left ordinate represents the methylation levels of CG/CHG, and the right ordinate represents the methylation levels of CHH. The dotted, green, vertical line represents the TSS, and the red, orange and blue solid lines represent CG, CHH and CHG, respectively, which show the methylation levels fluctuating in the different regions
