Genetic Mapping and Diversity in Plants and Animals

Summary At the instigation of the South Devon Cattle Breeders' Society of South Africa we studied the genetic relationships of South Devon cattle (South Africa) and Gelbvieh cattle (Germany) with eight other breeds including Red Angus and Black Angus (USA). On the basis of comparisons at ten immungenetic loci Gelbvieh and South Devon cattle are nearly as genetically similar as Red and Black Angus. The results indicate that Gelbvieh and South Devon had a common ancestry on the Continent and are distinct from other British breeds such as Hereford, Angus and Jersey. This study illustrates the application of studies of the genetic similarities of different breeds to the rational development of future breeding and preservation programs.
