INHERITANCE OF WAXY ENDOSPERM IN MAIZE. 
deviation of this percentage from 50 per cent is insignificant. 
\ 
29 
The 
percentage of waxy seeds has been determined as 23.9 per cent for 
the 198 ears expected to have 25 per cent of the seeds waxy. 
The proportion of gametes bearing the waxy character to the 
gametes bearing the horny character necessary to account for 23.9 
per cent of waxy seeds on self-pollinated ears is 48.9 to 51.1. 
The 131 ears on this basis are expected to have 48.9 per cent of 
waxy seeds. 
The deviation of the observed from this percentage 
would be expected to oceur as the result of chance once in 25,000 
times.

SUMMARY OF THE INHERITANCE OF WAXY ENDOSPERM. 
A large amount of data has been secured that confirms previous 
observations on the inheritance of the waxy endosperm which had
