Intermediateness is recorded in less than one fifth 

 of the reactions ; excess and deficit tivity is almost 



twice as frequent as interim - >; and sameness as 



the pollen parenl is noted as often as intermediateness

Beed parent has exercised very little influence on the 

 properties of the starch of the hybrid.
