Association of Polymorphisms in the Calpain I Gene with Meat Quality Traits in Yanbian Yellow Cattle of China (Report‪)‬

INTRODUCTION Yanbian yellow cattle are one of the most famous native cattle breeds in the Northeast of China. The breed has a long history of evolution. For a long time, this cattle breed has been used as farm cattle and strong draught animals. In recent decades, the cattle have been found to have high quality meat. Thus, Yanbian cattle are a rich genetic resource. Ten years ago, the blood protein polymorphism technology was first used to study the origins and genetic variability of these cattle, which indicated that Yanbian cattle have a close relationship with Korean yellow cattle breeds and that they contain Bos taurus blood. As molecular biology technology developed, DNA polymorphism has been widely used in the study of animal breed resources.
