Histone mark distributions. Box plots of ChIP input DNA intensities (log2) (A), H4K16ac ChIP/input ratios (log2) (B), H3S10ph ChIP/input ratios (C) and H3K4me2 ChIP/input ratios (D) in male (left) and female (right) adult flies separated by chromosome arms (X chromosome in red). See Figure 1 for box plot format. (E-J) The distributions of ChIP/input ratios for chromosome arms were compared inter se. Box plots of Bonferroni corrected P values from KS tests of ChIP/input ratios in all ChIP-chip replicates in male (E-G) and female (H-J) adult flies are shown. See Figure 1 for box plot format. P Values < 10-15 are off-scale (red arrow).
