Fig. 3. An illustration of how environment may alter a character. This var- 
iety of corn has ears which remain white under normal conditions, but when 
allowed to mature in the sunlight by removing the husk, they color red. Enclosing 
an ear in black paper, with the word "sun” cut out, gave the above result, the ex- 
posed portions being red, the unexposed grains remaining white. After Emerson. 
Fig. 4. Mendelian inheritance of the "podded" character in corn. The first 
hybrid generation above, from a cross of pod and ordinary corn: the four ears 
beneath representing the character of the K 2 or second hybrid generation. In 
pod corn, each grain is enclosed by a husk. After East and Hayes.
