A new high-frequency allele of the BM2113 locus in the Yunnan mithun population

Abstract

ABSTRACT. The BM2113 locus was amplified in Yunnan mithun (Bos frontalis) from the southwest mountains of China. It showed a high degree of polymorphism with a total of 12 alleles. The 121-bp polymorphic allele of the BM2113 locus that accounted for 37.1% of homozygotes was the predominant allele with a frequency of 58.57%, identified as mithunspecific for Bos species in Yunnan mithun. The polymorphism information content value was high with a mean of 0.6170, the expected and observed heterozygosity was moderate with values of 0.6427 and 0.6000, respectively, and the BM2113 locus was under Hardy-Weinberg equilibrium (P = 0.2897) in the Yunnan mithun population. This study elucidated the genetic diversity, multi-origin, specific alleles, and characterization of mithun.
