Problems solved by technology

Local breeds are usually welcomed by farmers and consumers in livestock production, but in recent years sheep hybridization has led to the disappearance of some local breeds, and the protection of local breeds is imminent
But so far there is no report that the SNP site of this gene is related to Mongolian sheep, Tibetan sheep and small-tailed Han sheep horn type

Abstract

The invention relates to an SNP marking composition related to a sheep horn phenotype. The SNP marking composition is located on a sheep RXDP2 gene and comprises RXDP2-SNP1 and RXDP2-SNP2; according to the annotation (XM_015097982) of a database latest version RXDP2 of the National Center for Biotechnology Information (NCBI), C->T mutation at the chr10: 29439053 (1999) locus serves as the RXDP2-SNP1, and C->T mutation at the chr10: 29439007 (1957) locus serves as the RXDP2-SNP2. By means of the SNP marking composition, the phenotypic characteristics of sheep horns can be identified, and therefore animal production and local variety protection can be guided; particularly, pure line Tibetan sheep can be identified by means of the SNP marking composition. Meanwhile, the loci have the greater scientific research value, and some genetic evolutionary laws can be researched through the obvious horn phenotype model.

Description

technical field [0001] The invention belongs to the field of genetic biology, and in particular relates to the RXFP2 gene SNP marker combination and application thereof related to the sheep horn phenotype. Background technique [0002] Sheep are the main animals raised in animal husbandry in my country, and their morphological characteristics are full body and dense hair. The head is shorter, and male sheep usually have spiral-shaped pointed horns. The main local breeds of sheep in my country include Mongolian sheep and Tibetan sheep. Among them, Mongolian sheep are mainly produced in the Inner Mongolia Autonomous Region, including small-tailed Han sheep, Hu sheep, Tan sheep, Ujimqin sheep, Bayinbulak sheep, etc. The horn type of Mongolian sheep is characterized by typical short and medium horns or no horns. Corner, the extension direction of the corner is to rotate close to the face. The types of Tibetan sheep mainly include grassland-type Tibetan sheep, Euler Tibetan sh...
