These results are suggestive in connection with the problem 

 of the absolute fecundity value of the same genes from dififerent 

 sources, a matter which will be fully discussed later. The fig- 

 ures give clear evidence of Mendelian segregation of high and 

 low fecundity. 



Matings of fi $ 5/(5 with Cornish Indian Game females. 

 There were but two matings of $ 576 with pure Cornish Indian 

 Game 2 ? which produced adult female offsprings. Other 

 matings were made but got no adult progeny. The successful
