  • Publication number: 20250061964
    Abstract: This invention relates to the field of genetic molecular breeding, specifically to a pig 50K liquid-phase chip based on multiple single nucleotide-polymorphism and its application. The probe design of the chip in this invention takes into account the distribution of captured SNP loci across the genome, the polymorphism of the loci, the quality of mSNP markers, and other issues, effectively avoiding problems such as uneven marker density and poor polymorphism. It also considers the quality of mSNP markers and the issue of linkage disequilibrium among mSNP markers. While adhering to the basic principles of liquid-phase chip design, genomic regions with moderate linkage disequilibrium between markers were selected, generating more SNP markers with high genotyping quality and moderate linkage disequilibrium within the probe region with the target loci. The mSNP liquid-phase chip of this invention expands the detectable number of SNPs to 1.
