Correlations between these ovarian methylomes and the densities of CpGs, genes and CGIs. (a) The global CpG methylation levels in Pre- (track 1), In- (track 2) and Post- (track 3) pubertal methylomes, from outside to inside, were quantified in per 1 Mb window. (b) The numbers of the differentially methylated CpG sites (DMCs) between Pre- vs. In- (track 1), In- vs. Post (track 2) and Pre- vs. Post (track 3), from outside to inside, were quantified per 1 Mb window. The densities of the CpGs (track 4), genes (track 5) and CGIs (track 6) in a and b were also quantified per 1 Mb window. The labels outside of track 1 represent the chromosomes in the pig genome. The methylation levels and density of DMCs were normalized by the number of CpGs in each window
