The theoretical numerical relation between the several color cembi- 
nations, in the order given above except that all greens are included in the 
last class, is 81:27:27:9:27:9:36:40, total 256. 
The distribution of the 353 individuals of the three F: progenies for 
which anther records were made (table 36, page 146) is compared below 
with the theoretical distribution. In order that all plants may be included, 
the few purple and sun red plants whose anther colors were not noted 
are arbitrarily distributed to the colored-anther and green-anther classes 
ina 3:1 ratio. The fit of observation to hypothesis is so good that there 
are three chances in five that the deviations may be due to errors of random 
sampling, P equaling 0.60.

When the six F2 progenies listed in table 35, for three of which no records 
of anther color were made, are grouped without reference to anther color, 
the comparison of observed and calculated numbers are as given below. 
For the six progenies there is practically an even chance that the devia- 
tions may be due to errors of random sampling, P equaling 0.48. It will 
be recalled that when these same progenies were compared with the dis-
