The expected percentage of white seeds is 50 and the observed 
50.1. Only one ear deviated from the expected percentage by three 
times the probable error, the remaining ears being very close ap- 
proximations of the 50 per cent. Ten ears were below, eight above, 
and two equaled the expected. The four groups of ears shown in 
this table are the reciprocals of the four groups shown in Table XXI. 
There are no significant differences between the groups, all showing 
a remarkable uniformity, the percentage of white seeds for the totals 
being exactly alike. The reciprocal groups are shown in Table 
XXIII. This is a striking contrast with the behavior of reciprocal 
groups in the progeny of Dh 234, in which a deficient number of male 
gametes bearing colorless aleurone were found.
