Mitochondrial DNA diversity in Nepalese goats

Abstract Text: The mitochondrial hypervariable (HVI) region sequence of 93 goats belonging to Khari, Chyangra, Terai and Sinhal breeds from different part of the country were partially sequenced to examine the phylogenetic relationship of Nepalese goat breeds. High mtDNA diversity among Nepalese goat breeds was observed and all goat haplotypes could be classified into four haplogroups (A-D). It appeared that mitochondrial lineage/ haplogroup A was observed in most of the Nepalese goats whereas only one breed (Chyangra) contains all four haplogroups. These sequences were compared with published sequences of domestic goats of neighboring countries (Bhutan, India, Pakistan and China) to determine the relationship of Nepalese goats among goat resources of the region. The study also revealed that the gene flow among the neighboring countries.
