Inheritance of Size 71 



Although some of these modifications are not de- 

 pendent upon the shelled condition, it is likely that 

 they are to be distinguished as having to do with "cyto- 

 plasmic activities" primarily, in the sense that they 

 modify the expression or realization of genotypic char- 

 acters without modifying the ultimately transmitted 

 character. If the transmitted genetic constitution 

 were changed, it would hardly find its way back after 

 six months (figure 30) to its original quantitative size- 

 value.
