HEREDITY 



FIG. 478. Mendelism demonstrated in the inheritance of starchy and 

 non-starchy endosperm in Corn. In the top row, the ear c shows the immedi- 

 ate result obtained when the starchy parent (a) and non-starchy parent (6) 

 are crossed. It is evident that starchness is completely dominant, d, an 

 ear with F 2 kernels resulting from the cross, showing segregation of starchiness 

 and non-starchiness. Lower row, ears of plants grown from kernels of d. e, f, 

 and g, result from planting starchy seeds. One ear out of the three is pure 

 starchy, h, result from planting non-starchy kernels, showing that the non- 

 starchy kernels were pure for the recessive character. After East,
