STUDIES IN INHERITANCE OF CERTAIN CHARAC- 

 TERS OF CROSSES BETWEEN DAIRY AND BEEF 

 BREEDS OF CATTLE.* 



This constitutes a preliminary paper on the crossbred herd 

 now being brought together by the Maine Agricultural Experi- 

 ment Station for the purpose of studying some of the outstand- 

 ing problems of dairy husbandry. 



The first section of the paper is devoted to a study of the 

 inbreeding in the foundation herd. It is shown that the in- 

 breeding as measured by the best mathematical methods is no 

 greater than would be expected to occur in any of the modern 

 breeds when the animals were selected at random. Consequent- 

 ly it is safe to assume that the results of the study are not due 

 to the width of the crosses, for, as has been pointed out, a num- 

 ber of the animals famous in their breed have been far more 

 inbred than any of the parental stock used in these experiments. 



The individual records of the animals composing both the 

 parental generation and the first and second filial generations 

 are given. 



Black body color is dominant to the other colors in the 

 first generation. In the second generation an orange-coated
