“Regan was in need of a new home at only four months old; he loves people, dogs, horses, small animals, our reptiles and just about everything. His favourite activity is swimming followed by bubbles and he is very good at brain games.”

Through Regan’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.

Haplogroup

A1d

Haplotype

A11a/419

Map

A1d

Regan’s Haplogroup

This female lineage can be traced back about 15,000 years to some of the original Central Asian wolves that were domesticated into modern dogs. The early females that represent this lineage were likely taken into Eurasia, where they spread rapidly. As a result, many modern breed and village dogs from the Americas, Africa, through Asia and down into Oceania belong to this group! This widespread lineage is not limited to a select few breeds, but the majority of Rottweilers, Afghan Hounds and Wirehaired Pointing Griffons belong to it. It is also the most common female lineage among Papillons, Samoyeds and Jack Russell Terriers. Considering its occurrence in breeds as diverse as Afghan Hounds and Samoyeds, some of this is likely ancient variation. But because of its presence in many modern European breeds, much of its diversity likely can be attributed to much more recent breeding.

A11a/419

Regan’s Haplotype

Part of the A1d haplogroup, this haplotype occurs most frequently in Yorkshire Terriers, Old English Sheepdogs, and Miniature Schnauzers.

Some other Embark dogs with this haplotype:

The vast majority of Rottweilers have the A1d haplogroup.

Through Regan’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.

Haplogroup

A2b

Haplotype

Hc.10

Map

A2b

Regan’s Haplogroup

A2b appears to have split a few times in succession, which means that some of the Central Asian male ancestors of this lineage went their separate ways before their respective Y chromosomes made their rounds. There is not much diversity in this lineage, meaning that it has only begun to take off recently. Two iconic breeds, the Dachshund and Bloodhound, represent this lineage well. Over half of Rottweilers are A2b, as are the majority of Labrador Retrievers and Cavalier King Charles Spaniels. While A2a is restricted mostly to East Asia, this paternal line is also found among European breeds.

Hc.10

Regan’s Haplotype

Part of the A2b haplogroup, this haplotype occurs most commonly in Labrador Retrievers, Rottweilers, Curly-Coated Retrievers, Dandie Dinmont Terriers, and village dogs throughout the world.

Some other Embark dogs with this haplotype:

A2b is found in the Daschund breed.
