SHOWING SHRUNKEN ENDOSPERM IN BOTH WHITE AND COLORED SEEDS 



The kernels on these ears show linkage of the shrunken endosperm character with two different 

 aleurone chamcters. (Aleurone is the thin external layer of the kernel containing the color 

 character.) The ear at the left is the result of crossing a hybrid plant with one that was pure 

 l?"" u°u '^j aleurone and non-shrunken endosperm. In this instance one of the parents of 

 the hybrid was white and shrunken and the other was colored and not shrunken. Again the paren- 

 tal combinations reappear, most of the white seeds being shrunken and the colored ones not In 

 the ear at the right the parent of the hybrid with non-shrunken endosperm also had white aleurone 

 JNote that very few of the white seeds are shrunken, showing that this aleurone factor also is linked 

 with the new character, shrunken endosperm. (Fig. 22.)
