Abstract

The invention provides an SNP locus related to hind leg length on the chromosome 6 of meat Simmental cattle and application of the SNP locus. The locus of an SNP marker is the 38696766th nucleotide locus on the chromosome 6 of the international cattle reference genome assembly UMD3.1 version, and the base of the locus is T or G. By optimizing the preferential alleles of the SNP, the frequency of the preferential alleles can be increased generation by generation, the hind leg length of the meat Simmental cattle is increased, and a genetic improvement progress of the cattle is accelerated, so that the economic benefit of beef cattle breeding is effectively improved.

Description

technical field [0001] The invention relates to the SNP site on the No. 6 chromosome of meat Simmental cattle related to the hind leg length and the application thereof. Background technique [0002] Meat Simmental is the most popular breed of cattle hybrids in China. It has the characteristics of fast growth and high meat production rate, so it is often used as the terminal male parent in breeding production. The length of the hind legs belongs to the carcass traits of cattle. Generally speaking, the beef cattle with long hind legs are larger in size, so the hind legs contain more meat. There are many genes controlling the length of hind legs in the bovine genome, and it is difficult for conventional breeding methods to rapidly accelerate their genetic progress. The rapid development of molecular marker technology provides the possibility for the precise selection of such traits. Genome-wide association analysis is based on the linkage disequilibrium between SNPs, through...
