A GENETICO-PHYSIOLOGICAL STUDY ON THE FORSrATION ETC. 



G7 



la bliu^ks, yellow, greon or brown is completely covei-ecl, but iu brown 

 gi-een colom* in visible, hence blue tinged gi-eens, blue tinged jellows, non tinged 

 gi-eens, nou tinged yellows, blncks and bi-owns arise by the ratio 27 : 9 : 9 : 3 : 

 12:4. If we denote alwve plienotypes by B.T.G., B.T.Y., (i, Y, BJ, and 

 Br. respectively, the following segregation is expacted in the F^ generation. 



The observed data showed a clos3 approximation to the above expectation. 

 See the table below.
