The same explanation will apply to all three ears, Nos. 1110, 1131, 
and 1134. Self-pollinated ears were obtained from the male and 
female parents of each of the ears, and the results showed all of the 
plants to be segregating in a regular manner, pr oducing the unit char- 
acter ratio of 3 colored to 1 white. 
It has been assumed that the hybrid Dh 234 was producing gametes 
CR Cr, and that the hybrid Dh 237 was producing gametes CR ch. 
Either hybrid, self-pollinated, would result in a monohybrid ratio, 
while if crossed it would result in ears with all of the seeds colored. 
If this assumption is correct the expected result of planting the seeds 
from a cross between two such plants and self-pollinating them would 
be one ear all colored, two having 3 colored seeds to 1 white, and one 
having 9 colored seeds to 1 white. 
PROGENY OF EAR NO. 1131. 
As only self-pollinated ears were obtained from the progency of 
ear No. 1131, these ears will be discussed separately. 
There were two classes of seeds on ear No. 1131, colored horny 
and colored waxy. These two classes were planted separately. The 
ears obtained from both classes are shown in Table XXIV. The 
upper group of four ears was obtained from self-pollinating plants
