A new colleague at the City of Hope and ultimately a lifelong friend, Susumu Ohno had recently demonstrated that the histologically observable Barr body present in the nuclei of mammalian female cells was a hyperchromatic X chromosome.
He also discovered in 1956 that the Barr body of mammalian female nuclei was in fact a condensed X chromosome.
In 1959 Susumu Ohno showed that the two X-chromosomes of mammals were different: one appeared like the autosomes; the other was condensed and heterochromatic.
