A significant part of the genes on the X chromosome are dosage compensated, unbound by MOF and not H4K16 acetylated in salivary glands. Male minus female expression (log₂) of all genes expressed in both sexes plotted versus MOF gene binding values on (A) the X-chromosome and (B) chromosome 3L. Horizontal dotted grey lines indicate ± one standard deviation from the mean expression ratio for chromosome 3L and vertical lines the mean MOF binding on chromosome 3L plus one standard deviation. (C) Average H4K16ac in four non-overlapping groups with different levels of MOF binding, (Unbound n = 122, >3 n = 220, >4 n = 227, >5 n = 227).
