All of the emphasis during the early history of the field of genetics 

 was placed upon the kijid of researches dealt with in the first papers 

 of this collectio?i. The authors were concerned primarily with what 

 was inherited and how. Their informatio?i came principally from the 

 final stages of the organism's development, whe?j it was fidly adidt, 

 and all of its perma72ent characteristics were fixed ajid recognizable. 

 All of this assumes a direct relationship between the gene and its 

 characteristic expression, but the pathways the ge?ie took in produc- 

 ing that expression had not been i?]vestigated, primarily because of
