B) Average composite plots of sub-nucleosomal MSL2 MNase-ChIP-seq (DNA) centered at PionX (left) or HAS (right) in early and late mixed-sex embryos. Total number of PionX = 56 and HAS = 247. Graph represents average IP/Input signal of 3 biological replicates. Shaded area indicates the 95% confidence interval across sites.
