320 Ever-sporting Varieties 



remaining individuals sporting into the oppo- 

 site group. 



In the following year I continued the experi- 

 ment with the seeds of the offspring of the red 

 bud-variations. The striped individuals gave 

 95^, but in the red ones only 84^ of the progeny 

 remained true to the parent type. 



From these figures it is manifest that the 

 red and striped types differ from one another 

 not only in their visible attributes, but also in 

 the degree of their heredity. The striped in- 

 dividuals repeat their peculiarity in 90 - 98^ of 

 their progeny, 2 - 10^ sporting into the uniform 

 red color. On the other hand the red individ- 

 uals are constant in 71 - 84^ of their offspring, 

 while 16-29% go over to the striped type. Or, 

 briefly, both types are inherited to a high degree, 

 but the striped type is more strictly inherited 

 than the red one. 



Moreover the figures show that the degree of 

 inheritance is not contingent upon the question 

 as to how the sport may have arisen. Bud- 

 sports show the same degree of inheritance as 

 seed-sports. Sexual and asexual variability 

 therefore seem to be one and the same process 

 in this instance. But the deeper meaning of 

 this and other special features of our genealog- 

 ical tree are still awaiting further investigation. 

 It seems that much important evidence might
