Etymology
    
Named by Hermann Henking in 1890 from x (signifying the unknown) due to some baffling properties he had observed. The brief resemblance in the appearance of the X and Y chromosomes to the letters "X" and "Y" respectively during cell division is entirely coincidental.[1]
Noun
    
X chromosome (plural X chromosomes)
- (genetics) A mammalian sex chromosome. Cells of females have a pair of X chromosomes while cells of males have an X and a Y.
