title: Mitochondrial DNA analyses of Indian water buffalo support a distinct genetic origin of river and swamp buffalo.
abstract: Water buffalo (Bubalus bubalis) is broadly classified into river and swamp categories, but it remains disputed whether these two types were independently domesticated, or if they are the result of a single domestication event. In this study, we sequenced the mitochondrial D-loop region and cytochrome b gene of 217 and 80 buffalo respectively from eight breeds/locations in northern, north-western, central and southern India and compared our results with published Mediterranean and swamp buffalo sequences. Using these data, river and swamp buffalo were distinguished into two distinct clades. Based upon the existing knowledge of cytogenetic, ecological and phenotypic parameters, molecular data and present-day distribution of the river and swamp buffalo, we suggest that these two types were domesticated independently, and that classification of the river and swamp buffalo as two related subspecies is more appropriate.
