*In 1921, the percentage of rough, medium, and smooth ears was determined 
for the progeny of each type of ear planted. 
The percentages of rough, medium, and smooth ears harvested from the 
large rough, small rough, small smooth, long smooth, and original unselected 
corn planted were respectively: 52, 35, and 13; 50, 33, and 17; 13, 39, and 
38; 16, 40, and 44; 30, 38, and 32.
