High genetic diversity of Tibetan Mastiffs revealed by mtDNA sequences

Abstract

Many studies have been reported the origin and evolution of domesticated animals, particularly dogs, however, few have systematically examined the Tibetan Mastiff (TM), a dog that lives primarily in the Qing-Tibet Plateau. Here, we study the origin and evolution of TM based on the population comparison of mtDNA D-loop sequences from TM and other dogs across the world. Intriguingly, non-simultaneous arrivals of Tibetan Mastiffs ancestors to Tibet occurred, which may result from continuous Tibetans’ settlement on Qing-Tibet Plateau supported by archaeological and genetic evidence. High genetic and haplotype diversity and robust haplotypes sharing with other dogs unique to East Asia are observed in Tibetan Mastiff, supporting that it is a very archaic breed derived probably from East Asia.
