Abstract

The invention provides a single nucleotide polymorphism (SNP) molecular marker related to a character of prolificacy during single birth of sheep, and a detection primer group, detection kit and application of the SNP molecular marker, and belongs to the technical field of sheep SNP molecular markers. Based on a sheep genome sequence information version number Oar_v4.0, the SNP molecular marker isobtained by A / G base mutation at the 29380965 bp site on the sixth chromosome of the sheep, and has significant correlation with the prolificacy character of the sheep. The lambing performance of thesheep to be tested can be determined by typing the SNP site. The method for detecting the genotype at the SNP site of the sheep is high in sensitivity, high in accuracy and higher in cost performance, and the SNP sites can be automatically detected. In a sheep breeding process, AA-type individuals can be selected, so that fecundity of the sheep is improved.

Description

technical field [0001] The invention belongs to the technical field of molecular markers and genetic breeding, and specifically relates to a SNP molecular marker related to the trait of single litter and multiple lambs in sheep, a detection primer set, a detection kit and applications thereof. Background technique [0002] Lamb size is a complex quantitative trait regulated by factors such as genetics, environment and hormone levels. Sheep is one of the excellent livestock species in our country. But its lambing and seasonal estrus greatly restrict the development of sheep industry. Therefore, increasing the number of lambs per litter is an important measure to improve the economic benefits of production. The application of genomics research can screen out candidate genes and molecular markers related to sheep reproductive traits at the level of the entire genome, enabling scholars to better understand the genetic mechanism of sheep's multiple lamb traits, which can contri...
