The single nucleotide polymorphism( SNP) of swine leukocyte antigen( SLA) gene is associated with the growth and development traits of swine. In this study,the partial sequence of SLA-DRB gene of 89 Aba Tibetan pigs( Pujiang county,Sichuan province) was sequenced to screen the stable markers for genetic breeding,and 14 loci of SNPs were identified. Based on the linkage relationships,these 14 loci of SNPs were allocated into 3 groups( loci group 1: g. 11470,g. 11945,g. 11997,g. 11387,g. 11369 and g. 11829; l...
