Density distribution of β-values. a Density distribution of β-values across all the 485,577 CpG sites of the 20 samples and the four pools. b Distribution of five samples of group A and their respective pool. c Distribution of five samples of group B and their respective pool. The black lines represent the distribution of pools and the grey lines represent the distribution of samples. The X-axis represents the average methylation β-value and the Y-axis the density
