 Table II gives the average results of F-j^, which 

 indicate in some way what has previously been demonstrated 

 in wheat crosses. 



Beardedness in F]^ is an intermediate character. 

 The results of Biffen^^ lead one to conclude this although 

 he classes beardedness aS recessive. He fails to count 

 in the bearded class the heads which are only slightly 

 bearded but places them in the class with the beardless. 

 It is probable all the results that have been obtained 

 are similar in regard to the beardedness being recessive 

 but the interpretation has been different. Wilson "-^"^ 

 like Biff en reports that awnlessness is dominant, giving 

 664 awnless and 207 awned. Bateson^-^-^^ also reports the 

 same thing but upon observation of the illustrations 

 given, it can be seen that some of those which he calls 



beardless possess beards, varing in number and length. 



IX 

 A like statement can be found which was made by Punnets . 



He fails to give any data to support what he assumes as 

 a fact, probably in part because he uses it only as an 

 argument for a theory which he was presenting. The work 

 of Alvin Keyser shows very conclusively that the result 

 when bearded andbeardless types are crosses is an inter- 

 mediate product. This is not based upon one cross but upon 

 many crosses and as his observations were upon the one charac- 

 ter they probably represent very accurately what really ex- 

 isted. In" F he found practically 25 'bGrrded^ 50 inter- 

 mediate; E5 beerdlees, the actual per cents being SI bearded
