SUMMARY OF THE INHERITANCE OF ALEURONE COLOR. 
The total number of ears expected to have 25 per cent of their 
seeds white was 168. This number includes both the second and the 
third generation of the two hybrids. The groups are shown in 
Table XXVIII. The 168 ears had a total of 81,336 seeds, with 25.5 
per cent white. This percentage is misleading, for, while it is only

Fic. 10.—Diagram showing the percentages of white seeds on 163 ears expected to have 
25 per cent of the seeds white compared with the normal probability curve. 
0.5 per cent above the expected ratio, the deviation for the number of 
seeds involved is almost five times the probable error. 
A deviation of this magnitude should not occur as the result of 
chance oftener than once in 666 times. The deviation, then, demands 
an explanation. That this deviation is not the result of a few 
aberrant ears is shown by the curves in figure 10. Only 11 of the 
163 ears deviated in excess of three times the probable error, and 
only 3 exceeded four times the probable error, although with 163
