THE THEORY OF THE GENE 



In the germ-track of the male and female the fragmen- 

 tation does not seem to take place, or if it does the pieces 

 rejoin before the maturation stage. 



The best evidence that the male bee is a haplont, or at 

 least that its germ-cells are haploid, is found in the be-

 division is abortive (Fig. 86, a, b). An imperfect spindle 

 forms in connection with 8 chromosomes. A piece of the 

 protoplasm constricts off without chromatin. A second 

 spindle develops and the chromosomes divide (Fig. 86, 

 d-g), presumably by splitting lengthwise, and the daugh-
