(c) Fs Generation. 



Seeds were obtained from 31 J^2 plants, with which to study the F^ 

 generation. The following are the results of these studies. 



1. Leaf -colour. 



It will be seen from Table VII that in respect to leaf-colour we 

 have obtained exactly the same results as in F^ (compare Table II).

From their behaviour in F^ it was apparent that 20 of the 31 jPa 

 plants were homozygous for leaf-colour. Of these 10 were green and 

 10 were yellow. Table VIII gives the total number of F^ plants 

 obtained from these 20 homozygous F^ individuals.
