Expectation: 50 starchy 50 sugary: 



i r<h \ and sugary grains were again very easily distinguish- 

 able. 



The grains were intermediate in size between those of the 

 (larger) sugary parent and those of the original pop corn. The 

 consistency of the starchy grains was less hyaline than thai 

 characterizing the pop corn, being intermediate between that 

 "I the latter and that of a typical Hint grain. 



Expt. 19. — Table 4 shows the result of the same cross as 

 the last in the case of the offspring of a particular grain of 

 the original sample of yellow pop com (I') which by the 

 behaviour of its offspring in Fl was shown to have arisen by 

 crossing with a white starchy strain of some kind. (See also 

 Expt. 'V2.) As far as the characters now under consideration 

 arc concerned its behaviour is normal.
