CHAPTER V 

 GENETICS AND BREEDING 1 



ONE of the primary purposes for which the 

 American Breeders' Association was founded was 

 to bring together on a common ground those who 

 were approaching the problem of the improvement 

 of plants and animals by breeding, on the one 

 hand, from the side of practical breeding, and, 

 on the other hand, from the side of the scientific 

 study of heredity. One of these groups stands as 

 the representative of the art or craft of breeding, 

 and the other as the representative of the science 

 of genetics. That each of these two bodies of 

 men has something to learn from the other there. is 

 no doubt. Even with the continued and prosper- 

 ous existence of such an association as this it is 

 certain that actually there is far from being any- 

 thing like as extensive a mutual interchange of 

 knowledge and opinion between science and prac- 

 tice in breeding as would appear from every point 

 of view to be desirable.
