SCOPE OF GENETICS 29 



perhaps Ave may call it — never goes into the 

 same germ-cell as the ingredient which makes 

 the standard erect. There are plenty of ways 

 of testing the truth of this interpretation. 

 For example, it follows that the purple 

 erects from such a family >vill in perpetuity 

 have offspring 1 purple hooded: 2 purple 

 erect : 1 red erect; also that all the white 

 hooded crossed with pure reds will give 

 purples, and so on. These experiments have 

 been made and the result has in each case 

 been conformable to expectation. 



Between these two factors, the purpleness 

 and the erectness of standard, some antago- 

 nism or repulsion must exist. In some way 

 therefore the chemical and the geometrical 

 phenomena of heredity must be inter-related. 



Some one will say perhaps this is all very 

 well as a scientific curiosity, but it has nothing 

 to do with real life. The right answer to such 

 criticism is of course the lofty one that science
