12 Flower Colour and Characters of the Opium Poppy 



In these the ratio 1 : 2 is very nearly attained between the R and 

 GPG forms, while the deficiency in the number of purples remains very 

 marked. 



The figures yielded by the crosses are in similar accord with the 

 explanation offered.

Here again the deficiency in the number of whites and purples is 

 less marked and confirms our previous conclusion that the effect is 

 traceable to the soil in which the F^, crop was grown. 



In the latter case we have an example of the direct synthesis of the 

 R form.

(6) The \- factor impure, LI. 



The evidence derived from families in which the L factor appears to 

 be impure is contained in the following table : 



The recorded results are thus in fair agreement with expectation 

 based on the assumption that the L factor is of the nature of an 

 intensifier, the main point of divergence being the large excess of RB 

 forms.
