Summary The domestic goat is one of the most important livestock species, but its origins and genetic diversity still remain uncertain. Multiple highly divergent maternal lineages of goat have been reported in previous studies. Although one of the mitochondrial DNA lineages, lineage B , was detected only in eastern and southern A sia, the geographic distribution of these lineages was previously unclear. Here, we examine the genetic diversity and phylogeographic structure of A sian goats by mitochondrial DNA sequences and morphological characteristics. The analyses of a total of 1661 A sian goats from 12 countries revealed a high frequency of lineage B in S outheast A sia. The frequency of this lineage tended to be higher in mountain areas than in plain areas in S outheast A sian countries, and there was a significant correlation between its frequency and morphological traits. The results suggest an original predominance of lineage B in S outheast A sia and the recent infiltration of lineage A into S outheast A sian goats.
