INHERITANCE OF WAXY ENDOSPERM IN MAIZE. 21 
The percentage of waxy seeds in Table VI is the percentage of 
male gametes bearing this character, while the percentage of waxy 
seeds in Table VII is the percentage of female gametes bearing the 
waxy character. 
The difference between these reciprocal groups is very small, indi- 
cating that for the progeny of the hybrid Dh 237 there is little or 
no difference in the percentage of male and female gametes bearing 
waxy endosperm. 
The fact is further demonstrated when the individual groups are 
examined. Table VIII gives the percentage of waxy seeds for the 
four pairs of reciprocals, with the differences between them.

In the first instance the percentage of waxy seeds is lower when 
heterozygous plants were used as male parents, but in the next two 
pairs of reciprocals this condition was reversed, the percentage of 
waxy seeds being higher when heterozygous plants were used as the 
male parents. 
In none of the pairs of reciprocals was a significant difference 
found, so that the percentage of male and female gametes bearing 
waxy endosperm may be said to be alike for the progeny of the 
hybrid Dh 287. 
In this regard the progeny of the two hybrids differ. The progeny 
of the hybrid Dh 234 showed that a significant deficiency of male 
gametes bearing the waxy character occurred, while no such de- 
ficiency is found on the progeny of the hybrid Dh 237. 
CROSSES BETWEEN THE TWO HYBRIDS DH 234 AND DH 237. 
Three of the ears that were selected for planting were the result — 
of crossing the two hybrids Dh 234 and Dh 237. These ears are 
Nos. 1110, 1131, and 1134 (Table I). 
As only self-pollinated ears were secured from ear No. 1181, the 
progeny of this ear is discussed separately from the progenies of 
ears Nos. 1110 and 11384.
