Kar No. 1110 and the two self-pollinated ears secured from the 
parents are all approximations of the expected 25 per cent. This is 
not true of ear No. 1134. The diagram shows that the female parent 
of the self-pollinated ear No. 1134 was a close approximation to the 
expected 25 per cent, while the self-pollinated ear from the male parent 
was below the expected by 3.1 per cent, which is almost three times 
the probable error. Although both parents could reasonably be said 
to approximate the expected 25 per cent, ear No. 1134 is below the 
expected by 8.7 per cent, which is 6.1 times the probable error. 
There seems to be no very good explanation of this departure, 
either the female gametes selected male gametes bearing the horny 
endosperm or a differential death rate prevailed for the zygotes with 
waxy endosperm. 
There was no difference in the behavior of the progeny of ears 
Nos. 1110 and 1134. The ears secured from self-pollinating plants 
grown from the horny seeds of No. 1134 bore 2,277 seeds, of which 
25.5 per cent were waxy, the deviation being less than the probable 
error. Only one ear of the five secured deviated in excess of three 
times the probable error, and that ear, No. 1923 (Table XI), was in 
excess of the expected. 
The 10 ears representing the progeny of ear No. 1134 that were ex- 
pected to have an equal number of waxy and horny seeds had 4,943 
seeds, with 49 per cent waxy. The deviation of 1 per cent is but 2.1 
times the probable error. The progeny of ear No. 1134 failed to 
throw any light on the observed deficiency of waxy seeds in the 
parent ear. | 
The two ears, Nos..1110 and 1134, that represent crosses between 
the two hybrids had but two classes of seeds, colored horny and 
colored waxy. These classes were planted separately. As no signifi- 
cant differences were found in the behavior of the progeny of the two
