GUCY1A1 gene specific SNP marker, Hetian city Qiaodahong sheep lambing number character detection method and application thereof

The invention discloses a GUCY1A1 gene specific SNP marker, a Hetian city Qiaodahong sheep lambing number character detection method and application thereof and relates to the field of molecular breeding. The SNP marker is derived from a sheep GUCY1A1 gene, the SNP marker is located at a position 43266624 on a chromosome No.17, the original basic group is C, and the variant basic group is T. The nucleotide sequence of the SNP marker is SEQ ID NO.1. The lambing number of a CC genotype individual with an SNP site is significantly greater than that of a TT genotype individual. The nucleotide sequence of a primer is SEQ ID NO.2-4. The SNP marker, the primer and the kit are applied to Hetian sheep lambing number character detection, and the lambing number characters of Hetian sheep to be detected are determined by detecting the SNP marker genotype. The SNP, the primer, the kit and the detection method can be used for breeding and screening of varieties with greater lambing number. 本发明公开了一种GUCY1A1基因特异SNP标记、和田乔达红羊产羔
