MATURATION DIVISIONS IN ASCARIS 



211 



FIG. 91. Diagram showing the distribution of the chromosomes in the two 

 maturation divisions of the male (cf ) and female (?) germ cells of the nematode 

 worm Ascaris. The light spot at the end of some of the chromosomes may 

 represent a group of characteristics (e.g., sexual characters), and its distribution 

 to spermatozoa and mature eggs is shown in the history of the two divisions.
