Through Hef’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.

A1a

Jacks Wild International Playboy’s Haplogroup

A1a is the most common maternal lineage among Western dogs. This lineage traveled from the site of dog domestication in Central Asia to Europe along with an early dog expansion perhaps 10,000 years ago. It hung around in European village dogs for many millennia. Then, about 300 years ago, some of the prized females in the line were chosen as the founding dogs for several dog breeds. That set in motion a huge expansion of this lineage. It's now the maternal lineage of the overwhelming majority of Mastiffs, Labrador Retrievers and Gordon Setters. About half of Boxers and less than half of Shar-Pei dogs descend from the A1a line. It is also common across the world among village dogs, a legacy of European colonialism.

A232

Jacks Wild International Playboy’s Haplotype

Part of the large A1a haplogroup, this haplotype occurs in village dogs in the South Pacific, as well as Bosnia and Herzegovina. Among breed dogs, this haplotype is most frequent in Labrador Retrievers, Yorkshire Terriers, and Maltese.

Shar Pei dogs think A1a is the coolest!

Through Hef’s Y-chromosome we can trace his father’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.

A1a

Jacks Wild International Playboy’s Haplogroup

Some of the wolves that became the original dogs in Central Asia around 15,000 years ago came from this long and distinguished line of male dogs. After domestication, they followed their humans from Asia to Europe and then didn't stop there. They took root in Europe, eventually becoming the dogs that founded the Vizsla breed 1,000 years ago. The Vizsla is a Central European hunting dog, and all male Vizslas descend from this line. During the Age of Exploration, like their owners, these pooches went by the philosophy, "Have sail, will travel!" From the windy plains of Patagonia to the snug and homey towns of the American Midwest, the beaches of a Pacific paradise, and the broad expanse of the Australian outback, these dogs followed their masters to the outposts of empires. Whether through good fortune or superior genetics, dogs from the A1a lineage traveled the globe and took root across the world. Now you find village dogs from this line frolicking on Polynesian beaches, hanging out in villages across the Americas, and scavenging throughout Old World settlements. You can also find this "prince of patrilineages" in breeds as different as German Shepherds, Golden Retrievers, Pugs, Border Collies, Scottish Terriers, and Irish Wolfhounds. No male wolf line has been as successful as the A1a line!

H1a.1

Jacks Wild International Playboy’s Haplotype

Part of the large A1a haplogroup, this common haplotype occurs in village dogs all over the world (outside of Asia), with many occurring in Central and South America. We have found this haplotype frequently in Bernese Mountain Dogs, Australian Shepherds, and Boston Terriers.

Dogs with A1a lineage travelled during European Colonial times.
