SNP (Single Nucleotide Polymorphism) molecular marker for identifying lambing number character of meat merino and application of SNP molecular marker

The invention belongs to the technical field of molecular genetics, and particularly relates to an SNP (Single Nucleotide Polymorphism) molecular marker for identifying the lambing number character of meat merino and application of the SNP molecular marker. The molecular marker disclosed by the invention is cloned from a BRIP1 gene (Gene Bank: 101107879), and is positioned at the basic groups of the 11098497 site and the 11098533 site on the 11th chromosome of the international sheep genome Oarv4.0 version, and the mutant basic groups are A or G; the invention also relates to a specific primer pair for detecting the SNP molecular marker by using a PCR (Polymerase Chain Reaction) technology and an SNP detection method. SNP locus detection is used for carrying out early selection of the meat merino lambing number character, shortening the breeding period and accelerating the breeding process, a meat merino lambing number character early selection technology is established, the breeding time of the excellent mea
