Abstract:

Single nucleotide polymorphisms (SNP), as a third generation molecular marker, has many characteristics, such as rich sites, strong representation and genetic stability, it had became the focus of molecular markers related fields. This paper reviewed the characteristics and detection methods of SNP and its application in beef cattle’s growth traits, reproductive traits, carcass and meat quality traits, as the candidate gene for molecular marker assisted selection, to accelerate the speed of beef cattle breeding.
