Abstract

This article describes the complete sequences of the mitochondrial DNA displacement loop (D-loop) region and cytochrome b gene from domestic goats in Laos (Laos native) and wild goat “markhor” (C. falconeri). The wild goat “bezoar” (Capra aegagrus) has been considered to be the strongest candidate for the ancestor of the domestic goats (C. hircus); however, there is not sufficient molecular data to verify the hypothesis at present. In phylogenetic analyses, two wild goats, the markhor and the ibex (C. ibex), appeared as an outgroup, while the bezoar was located in a cluster of domestic goats. Mitochondrial haplotypes of Laos natives revealed two distinct major clusters: one was the same as the bezoar, the second, unique to Laos natives. The topology and calibrated levels of sequence divergence suggests that these clusters might represent at least two different subspecies of ancestral bezoars.
