It is apparent from the above Table that in green plants the ratio 

 magenta : scarlet : dark-red is 6:2:4, and that in yellow plants the 

 ratio magenta : scarlet is 3 : 1, so that we must consider that the genetic 

 constitution of the plant used is GgDDBbMM. 



2. Oreen 'plant with deep magenta flower. 

 The results are indicated in Table VI. 



It will be seen from the above Table that the ratio green, deep 

 magenta : green, deep dark-red : yellow, deep magenta is 2:1:1. Thus 

 we may consider the genetic constitution of the plant used to have been 

 GgDDBBmm.

From the above Table we see that in green plants light scarlet : 

 scarlet : deep scarlet : light dark-red : dark-red : deep dark-red : white are 

 in the ratio 12:6:6:6:3:3:12, and in yellow plants light scarlet: 

 scarlet : deep scarlet : white are in the ratio 6:3:3:4. Thus the genetic 

 constitution of the plant used must have been GgDdbbMm.
