ij.eshed fore quarters are transmitted to the offspring when either 

 rarent is of the Aberdeen-Angus breed. The body and hind 

 uarters appear intermediate but in most cases resemble the 

 «airy parents. 



"Data are given on the milk and fat production of some 4 

 ■f the crOss-breds. The results indicate that milk and fat pro- 

 uction are inherited separately. High milk production is domi- 

 nant to low, high fat per cent is recessive to a low fat per cent 

 1 the milk. Put in less technical language the results of this 

 ross indicate that in a cross between an animal from a high 

 ailking strain mated to one of a low milking strain, the result- 

 ng female offspring will have the milk production of the high 

 train. In a cross between animals one of which is from a high 

 sst line and the other from a low test line the resulting offspring 

 nil have a butter-fat test of the low test line. The number of 

 hese milking first generation females is not great enough to 

 lake this statement an absolutely sure conclusion." 



Inheritance of Twinning and Problems Connected 

 Therewith 



During the past year a new project to obtain information 

 if the frequency of twinning in cattle has been set in operation, 

 n all some 500 of progressive breeders of the United States 

 lave responded with some very excellent data on this subject, 

 t is, of course, too early to have analyzed the results obtained 

 rom this investigation. Some idea of the scope of the informa- 

 ion may be had by a glance at the reproduction of the form 

 ised as shown below.
