ears, they will be considered together. The ears secured from the 
progeny of Nos. 1110 and 1134 are shown in tables X and XI. The 
ears resulting from pollinating homozygous waxy plants with heter- 
ozygous horny plants are extremely variable. Five of the eleven 
ears deviated from the expected percentage in excess of three times 
the probable error. With the exception of the ears shown in Table 
X the remaining ears show no significant deviation.

The two groups in Table XI are the reciprocals of the two groups 
in Table X and since one parent is homozygous for waxy endosperm 
it is again possible to determine whether a difference exists in the 
percentage of male and female gametes bearing the waxy endosperm. 
The ears in Table X show the proportion of waxy to horny endo- 
sperm in the male gametes, while the ears in Table XI show the 
proportion of waxy to horny endosperm in the female gametes. 
Table XII shows the differences observed in the reciprocal groups. 
Table XII shows that a difference exists between the male and 
female gametes in the proportion of gametes bearing waxy endo- 
sperm, the male gametes bearing the waxy character being deficient.
