Figure 2.

Venn diagrams representing overlaps of significant histone peaks, annotated CpG islands, and putative promoters used to identify candidate-imprinted genes. A) Significant peaks for H3K4me3 (dark green), H3K9Ac (light green) and H3K9me3 (red). B) Overlaps of H3K4me3 (green), annotated CpG islands (yellow), and putative promoters (blue). C) Overlaps of H3K4me3 + H3K9Ac peaks (green), all three histone modification peaks (red), all three histone modification peaks and CpG islands (blue), and all elements and putative promoters which represents the list of candidate imprinted genes (light green).
