Henking (1891) could trace a specific nuclear structure all through spermatogenesis in a few insects, and it was also
observed by him that 50 per cent of the sperm received this structure after spermatogenesis, whereas the other 50 per cent sperm did not receive it. Henking gave a name to this structure as the X body but he could not explain its significance.
