Molecular marker related to sheep growth traits and application thereof

The invention discloses a molecular marker related to sheep growth traits and application thereof, and belongs to the technical field of molecular markers. The invention discloses molecular marker sites related to growth performance in sheep and a detection method, namely, the genotype of the g.32392979 site and the genotype of the g.32394969 site of SNP sites in an intron region of a KIF5B gene of the sheep can influence the weight of the sheep, and the molecular marker sites can be used for breeding of the sheep. The invention further provides a primer pair for detecting the SNP molecular marker of the sheep growth traits, after amplification, a product is subjected to sanger sequencing, the genotype of the g.32392979 site and the genotype of the g.32394969 site of the SNP sites in the intron region of the sheep KIF5B gene are determined, TT and GG are growth trait dominant genotypes, and the genotype of the g.32394969 site of the SNP sites in the intron region of the sheep KIF5B gene is determined.
