This text-book deals first with the fundamental questions of in- 

 heritance common to plants and animals, but emphasizes the prin- 

 ciples, methods and practices which are peculiar to animal breeding. 



The improvement of the domestic animal resulting in the develop- 

 ment of highly specialized qualities useful to man is one of the most 

 notable achievements in modern agriculture. How, through man's 

 efforts, these highly specialized and valuable qualities have been 

 acquired, and how these qualities have come to be represented in 

 the constitution of the germplasm and thus transmitted from parent 

 to offspring, is a subject of great scientific and practical interest. 



The scientific principles which govern the practice of animal 

 breeding may all be classified under inheritance, reproduction and 

 development. The text emphasizes particularly those scientific prin- 

 ciples which are recognized as the basis of heredity and which have 

 been sufficiently well established to afford a real basis for the practice 

 of animal breeding. The ph3'-sical basis of heredity in the germplasm 

 of the cell and the significant changes resulting in transmission are 

 described and illustrated. 



The physiology of reproduction and its applications to the practice 

 of breeding is the subject of an important chapter. The interrela- 

 tions of heredity and development which constitute the real basis 

 of the breeder's art are discussed. The practical questions of in- 

 breeding, crossbreeding, grading, fertihty, sterility, and sex are con- 

 sidered in the light of the most modern development of biological
