As the principles that govern thcM? casr^ «•"• 

 of very wide application, it follows that t}i 

 very great advantage from the standpoint < 

 plant developer, in the discover}' of pairs of unit 

 characters and the demonstration of their rela- 

 tion toward each other as regard«« doniinKnce 

 and recesshreness. 



An interesting illustration of th ! 



by the experiments made by Professor V\ I 

 Biffin, of Cambridge University, in the mm - 

 cessful attempt to develop a new race of 

 wheat. 



Professor Biffin through a series of experi- 

 ments showed that when beardless ears of wheat 

 are crossed with bearded ones, the beardless 

 condition proves dominant, so that all the off- 

 spring are smooth-eared; but that the recessive 

 quality of bearded grain reappears in the secoml 

 generation. 



The same thing held true for various other 

 pairs of unit characters, such as red chaff versus 

 white chaff, red grain versus white grain, hollow 

 stem versus solid stem, and the like.
