the membrane layers that envelope the x chromatin at interphase remain associated with the x chromosome throughout gonial mitotic stages providing the ultrastructural basis for the apparent negative heteropycnosis observed with the light microscope. -- the x chromosome is inactive in rna synthesis during gonial mitotic stages but is hyperactive in rna synthesis when compared to autosomes at gonial interphase. -- x-chromosome condensation which reaches its maximum at premieotic interphase is initiated at or prior to the pre-pentultimate gonial division .
