BRAINERD: FOUR HYBRIDS OF VIOLA PEDATIFIDA ALY | 
normal average (one half of the whole number); instead of 8 of 
each we have 10 Aa’s, 12 Cc’s, and 10 Dd’s. And it should be 
remembered that this statement is not based solely on the appear- 
ance of the F, plant but on the fact that the reversionary charac- 
ters, A, C, D, were found to be stable in reproduction; while the 
hybrid characters were found to be unstable. For example, with 
the exception of no. 4, which had only two offspring, each of the 
ten Aa plants in brood 781 gave 2-7 plants with uncut leaves.

_ And not only in the second but also in the third generation of 
this hybrid the number of plants having the positive character 
seems to fall short of the Mendelian requirements. This appears if
