The data are presented in table 9. Four F,; progenies (group 1) were 
made up of the four color types Ia, IIIa, V, and VIb. The total numbers 
of plants of each of the four types, as seen below, were in close accord 
with expectation, P equaling 0.57. There is more than an even chance 
that such deviations as those observed may have been due to errors 
of random sampling. The comparison of observed with calculated results 
follows:

Three of the eight purple F;’s (group 2) gave in Fy only purple and 
dilute purple plants, 88 of the former and 28 of the latter. The expected 
numbers were 87 and 29, respectively, showing a deviation of 1 + 3.1. 
One of the eight F; purples (group 3) gave 67 purple and 21 brown 
plants in F;, while the expected numbers were 66 and 22, respectively. 
The deviation here is only 1 + 2.7. 
None of the eight F, purples bred true, but only one in nine was expected 
to do so. As already indicated, the theoretical distribution of nine Fs; 
purples of the sort here under consideration, with respect to the four 
kinds of behavior in Fy, is 1:2:2:4. The observed distribution was 
0:3:1:4. There is more than an even chance that these deviations may 
have been due to errors of random sampling, P equaling 0.57.
