Distinct regulation between the X chromosome and autosomes during the late stages of male germline. a GS, b PS, and c RS are shown. Average tag density (ATD) of each histone mark was compared between all autosomal genes and all X-linked genes. ATD, average tag density; GS, germline stem cells; PS, pachytene spermatocytes; RS, round spermatids; ChIP-seq, chromatin immunoprecipitation sequencing
