=== 1959 - Identification of the Inactivated X Chromosome ===
In 1959, Japanese geneticist [[Susumu Ohno]] demonstrated that the previously identified "nucleolar satellite" was in fact the inactivated X chromosome in female somatic cells.<ref name=":8">{{Cite journal |last=Miller |first=Fiona Alice |date=2006-09-01 |title='Your true and proper gender': the Barr body as a good enough science of sex |url=https://www.sciencedirect.com/science/article/abs/pii/S1369848606000446 |journal=Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences |volume=37 |issue=3 |pages=459–483 |doi=10.1016/j.shpsc.2006.06.010 |pmid=16980188 |issn=1369-8486}}</ref> Using chromosomal staining techniques in animal models, such as rodents, he confirmed its identity and named it the "Barr body" in recognition of Barr's earlier discovery.<ref name=":8" /> Ohno's work clarified that the Barr body was not merely a structural feature but represented the functional silencing of one X chromosome.<ref name=":8" />
