Fig. 64. Roan short-horn cow. Beef type. The fine mosaic of red and white spots indicates that this 

 animal is a heterozygote between red and white (Figs. Si and 63). 



Fio. 65. Ayrshire bull. Exteasive white spotting in this breed leaves only an occasional small spot 

 pigmented. The breed is hardy, " dual purpose " but inclining more to the dairy type, yet less spe- 

 cialized and better adapted to a severe climate than the Jersey and Guernsey breeds. It originated in 

 Scotland.
