(B) The initial clues about the genetic$/$chromosomal basis of sex determination were obtained from experiments carried out on insects.Henking $(1891)$ observed a specific nuclear structure during spermatogenesis in some insects.He observed that $50\, \%$ of the sperms received this structure,while the other $50\, \%$ did not.Henking named this structure the $X$-body,but he could not explain its significance.Later,other scientists concluded that the $X$-body observed by Henking was actually a chromosome,which was later named the $X$-chromosome.
