Through Leo’s mitochondrial DNA we can trace his mother’s ancestry back to where dogs and people first became friends. This map helps you visualize the routes that his ancestors took to your home. Their story is described below the map.

A4

Leo’s Haplogroup

The A4 maternal lineage is fairly rare. It is found in Cocker Spaniels, but A4 is also represented well among East Asian breeds including the Chinese Crested Dog, Shar-Pei and Shih Tzu. Moving away from Asia, it is also found among Chihuahuas (a very old breed!) and village dogs in Peru. This may be a lineage that moved into Western breeds because of their owners' tendencies to mix them up with Eastern breeds in the early modern period.

A454

Leo’s Haplotype

Part of the A4 haplogroup, the A454 haplotype occurs most commonly in Shih Tzus and Chinese Shar-Peis.

The popular Chihuahua breed descends from the A4 maternal line.

B

Leo’s Haplogroup

B is a relatively rare paternal line that has only recently started to expand. The dominant lineage among the ancient Shih Tzu breed, it is also found among Tibetan Spaniels. Outside of these two breeds, B seems to be a particularly common paternal line among the village dogs of India and Southeast Asia, though it is found as far afield as Africa and down into Oceania. Considering that it is particularly diverse in northern India, it could be that this lineage hung out mostly in South Asia after the expansion of domestic dogs from Central Asia. Because it is present in Mongolia as well, it may not be surprising that ancient East Asian dog breeds are also part of this lineage. Alternatively, perhaps males representing this lineage headed north out of southern Eurasia, which eventually gave rise to the Shih Tzu and may have inspired stylistic representations of lions in ancient China!

H15.7

Leo’s Haplotype

Part of the B haplogroup, this haplotype has been found in village dogs in Qatar and India. Unlike most other haplotypes within the B haplogroup, we do see this in a select few breed dogs. Specifically, it occurs in the Shih Tzu and Tibetan Spaniel.

The B Haplogroup is most commonly found the adorable Shih Tzu breed.
