Genetic diversiti of Bac Ha dog based on 582BP mitochondrial HV1 region sequence

Abstract

This study made an initial evaluation of the genetic diversities of Bac Ha dog population based on mitochondrial HV1 region sequence. The results showed that, in 15 sampled individuals, 11 different haplotypes of haplogroups A and B were identified. Notably, two novel haplotypes An1 and An2 (13.33% of the population), though not published in any previous studies, were found. Most haplotypes had similar shares in the Bac Ha dog population, while the uncommon ones (A44, A73, A85, A86, A121, A140) made up a proportion of up to 66.67%. Furthermore, analysis of basic genetic indexes such as haplotype diversity (0.952) and nucleotide diversity (0.00849) showed the relatively high genetic diversities of this breed. The study results will provide additional useful database for further genetic researches on mitochondrial genome of the Bac Ha dog population.
