Origin of Y chromosome
Named by Nettie Stevens in 1905 using the next letter in sequence following the naming by Hermann Henking in 1890 of the X chromosome. 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.
