Untersuchungen über den ersten Entwicklungsvorgänge in den Eiern der Insekten. II. Ueber Spermatogenese und deren Beziehung zur Eientwicklung bei Pyrrhocoris apterus.

L. Z. wiss. Zool., 51, 685-736, 1891.

In his study of the testicles of the firebug (Pyrrhocoris) Henking noticed that one chromosome did not take part in meiosis. He named this X element because its strange behavior made him unsure whether it was genuinely a chromosome. After it was established that the "X element" was indeed a chromosome it became known as the X chromosome.
