246 BREEDING 



of the first flower at a relatively high node on the 

 plant, which is the chief condition determining 

 lateness. The allelomorph to purpleness in the 

 flower is white, and the allelomorph* to highness of 

 node of first flower is lowness. In the second hybrid 

 generation, raised from a hybrid produced by crossing 

 a " high " purple with a " low " white, there is 

 evidently a strong tendency for purple to be associated 

 with " high " and white with " low." With a very 

 low percentage of exceptions, all the purples are 

 " high " and all the white " low " ; but there are 

 just a few " lows " amongst the purples, and a few 

 " highs " amongst the whites, which show that the 

 two characters are not associated so closely as, 

 for instance, purpleness of flower and purpleness 

 of axil. 



In conclusion it may be said that the urgent 

 need of the present is an exhaustive enquiry, under- 

 taken by independent observers, into the mode of 

 inheritance of the characters of domesticated animals 

 and plants. It will be time enough to systematise 

 this knowledge when there is more of it.
