AI Article Synopsis
- - The Korean native pig (KNP) is an important indigenous breed in South Korea, believed to have originated from Northeastern China and migrated to Korea around 3000 years ago.
- - The study analyzed genetic diversity and ancestry of KNP pigs using advanced techniques on a sample of 891 pigs from 47 different breeds around the world.
- - Findings revealed that KNP pigs are genetically closer to European breeds and exhibit a distinct genetic structure, supporting previous research on their unique ancestry.
Article Abstract
The Korean native pig (KNP; ) is an indigenous porcine breed in South Korea considered as a valuable but dwindling genetic resource. Studies using diverse methodologies and genetic markers suggest that this population originated from the Manchu province of Northeastern China and migrated approximately 3000 years ago into the Korean peninsula. This study aimed to verify those findings by performing diversity and ancestral analyses using the 60K single-nucleotide polymorphism (SNP) BeadChip on 891 pigs of 47 breeds worldwide. We also performed principal component analysis (PCA), ancestry analyses, phylogenetic tree analysis using SNPhylo, and linkage disequilibrium analysis. Furthermore, we generated heatmap, obtained Nei's genetic distance and values, and explored the heterozygosity of commercial and native Korean pigs. The results demonstrated that KNP pigs are more closely related to European breeds than to Chinese breeds. In addition, as previous studies have suggested, our admixture analyses indicated that KNP pigs showed distinguishable genetic structure.
