From: reChIP-seq reveals widespread bivalency of H3K4me3 and H3K27me3 in CD4+ memory T cells

(a) Boxplots of the G+C content in percentage, (b) the CpG content in percentage, (c) the CpG odds, that is, observed CpG count over the expected CpG count and (d) the CpA/TpG (deamination products of methylated CpGs) odds.
