X chromosome en · NOUN

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.

Meanings

1. A mammalian sex chromosome: in the XY sex-determination system, cells of females typically have a pair of X chromosomes, while cells of males typically have an X and a Y.
