128 Atavism. 
a beautiful typical plant with broad stripes but without 
any broad patches on the corolla, and fertilized it with 
its own pollen in a bag. In 1899 I raised from its seeds 
about 250 plants, which covered a bed of about four 
square meters, and nearly all of which flowered on the 
main stem and on several lateral branches. There were 
only a few finely striped individuals amongst them, 
whereas the majority were very coarsely marked. But 
the proportion of uniformly red plants was considerable: 
Striped individuals 160 64% 
Red individuals 91 36% 
Total 251 
That is to say, about one-third of the olants had re- 
verted to a uniform red color. 
The offspring of the almost yellow parents showed 
the following distribution of the various types of colora- 
tion (Bi--B4 refer to the individual seed-parents and to 
the groups of offspring arising from them) :

These tables, and Fig. 23 which has been constructed 
from them, show that two races have been produced by 
the selection and self-fertilization of the extreme variants.
