22 INHERITANCE IN SILKWORMS, I 



From these matings and results it seems obvious that what deter- 

 mines the behavior in inheritance of a character, that is, what deter- 

 mines its prepotency or lack of prepotency, its dominance or recessive- 

 ness, is something fully apart from (a) sex of the parent and (b) 

 physical vigor of the parent. In all the above matings the larval 

 character zebra striping is regularly dominant in all lots, whether the 

 parent representing the zebra larval characteristic be male or female, 

 vigorous or weak bodied.
