Solution:

The X body of Henking was observed in half of the sperms during spermatogenesis. During his experiments on insects, Henking found the traces of a nuclear structure all through the process of spermatogenesis which he named it as X body. He also observed that, after spermatogenesis, exact half of the sperms received this X body, while the remaining half did not. Later, scientists found out that this X body of Henking was actually a chromosome and hence, named it X-chromosome.
