RESULTS WITH HYBRIDIZATION 105 



All the hybrid kernels resemble the dent corn kernels, 

 so we apparently have three dent kernels to one sweet 

 kernel on each self-fertilized hybrid ear. If the seed of 

 one of these hybrid ears be sown, we apparently harvest 

 three starchy ears to one sweet ear, as follows : — ■ 



DOMINANT AND RECESSIVE CHARACTERS 



77. In the above example, every hybrid ear has a starch 

 grain and cannot be distinguished, on inspection, from a 

 pure starchy type. Starchiness in this case is dominant 

 over the sweet corn grain ; or, in an ear that is a hybrid 

 of dent corn and sweet corn, instead of the dent and 

 sweet corn types blending, thus giving an intermediate, 

 the dent completely dominates. In this case the sweet 

 corn is recessive. By experiment this quality has been 

 determined for many characters of maize, the following 

 being typical examples : — 



Red colors of cobs, stem, or husks dominant over green. 

 Starch endosperm dominant over sweet endasperm. 

 Yellow endosperm dominant over white endosperm. 

 Blue aleurone dominant over colorless aleurone. 

 Red pericarp dominant over colorless pericarp. 

 Podded kernels dominant over naked kernels.
