Molecular marker related to sow farrowing uniformity and obtaining method and application thereof

The invention relates to a molecular marker related to sow farrowing uniformity and an obtaining method and application thereof, and relates to the technical field of pig genetic genes. The molecular marker is an SNP (Single Nucleotide Polymorphism) molecular marker, the SNP molecular marker is positioned at the 54406034bp position of a pig 12 # chromosome, and the 54406034bp position of the pig 12 # chromosome is Cgt; and the pig reference genome is Sscrofa11.1 according to the mutation site of the T mutation. The farrowing uniformity of sows with different genotypes of the molecular marker has extremely significant difference, and the sow is selected according to the molecular marker, so that the variation coefficient of the farrowing birth weight of the sow can be reduced, the uniformity of piglets can be improved, and the survival rate of the piglets can be increased. 本发明涉及一种与母猪产仔均匀度相关的分子标记及其获得方法和应用，涉及猪遗传基因技术领域。该分子标记为SNP分子标记，所述SNP分子标记位于猪12号染色体54406034bp位置，所述猪12号染色体54406034bp位置为C>T突变的突变位点，猪参考基因组为Sscrofa11.
