Rhett

Mixed Ancestry

“I adopted Rhett from the Idaho Humane Society. He was named by his foster family after a YouTube show called Good Mythical Morning. Since I like that show I kept his name. He is very energetic and tug-of-war is his favorite game. He is very smart but stubborn. He is the best cuddler and loves attention.”

Health Summary

warn icon

Rhett inherited two variants that you should learn more about.

Progressive Retinal Atrophy, prcd

warn icon

Rhett inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Rhett’s health. This variant is inherited in an autosomal recessive manner, meaning that a dog needs two copies of the variant to show signs of this condition. Rhett is unlikely to develop this condition due to this variant because he only has one copy of the variant.

What is Progressive Retinal Atrophy, prcd?

PRA-prcd is a retinal disease that causes progressive, non-painful vision loss. The retina contains cells, called photoreceptors, that collect information about light and send signals to the brain. There are two types of photoreceptors: rods, for night vision and movement, and cones, for day vision and color. This type of PRA leads to early loss of rod cells, leading to night blindness before day blindness.

Progressive Retinal Atrophy, crd4/cord1

What does this result mean?

This variant should not impact Rhett’s health. This variant is inherited in an autosomal recessive manner, meaning that a dog needs two copies of the variant to show signs of this condition. Rhett is unlikely to develop this condition due to this variant because he only has one copy of the variant.

What is Progressive Retinal Atrophy, crd4/cord1?

PRA-CRD4/cord1 is a retinal disease that causes progressive, non-painful vision loss over a 1-2 year period. The retina contains cells, called photoreceptors, that collect information about light and send signals to the brain. There are two types of photoreceptors: rods, for night vision and movement, and cones, for day vision and color. This type of PRA leads to early loss of cone cells, causing day blindness before night blindness.

Through Rhett’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

A1e

Haplotype

A228

Map

A1e

Rhett’s Haplogroup

This female lineage likely stems from some of the original Central Asian wolves that were domesticated into modern dogs starting about 15,000 years ago. It seemed to be a fairly rare dog line for most of dog history until the past 300 years, when the lineage seemed to “explode” out and spread quickly. What really separates this group from the pack is its presence in Alaskan village dogs and Samoyeds. It is possible that this was an indigenous lineage brought to the Americas from Siberia when people were first starting to make that trip themselves! We see this lineage pop up in overwhelming numbers of Irish Wolfhounds, and it also occurs frequently in popular large breeds like Bernese Mountain Dogs, Saint Bernards and Great Danes. Shetland Sheepdogs are also common members of this maternal line, and we see it a lot in Boxers, too. Though it may be all mixed up with European dogs thanks to recent breeding events, its origins in the Americas makes it a very exciting lineage for sure!

A228

Rhett’s Haplotype

Part of the large A1e haplogroup, we have spotted this haplotype in village dogs in the Democratic Republic of the Congo and in the Dominican Republic. Among breeds, we see it frequently in big dogs like Saint Bernards, Leonbergers, and Great Danes. However, we also see it in small breeds including wire Fox Terriers and Rat Terriers. That’s a pretty wide size range!

Irish Wolfhounds are a consistent carrier of A1e.

Through Rhett’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.17

Map

A2b

Rhett’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.17

Rhett’s Haplotype

Part of the A2b haplogroup, this haplotype occurs most frequently in mixed breed dogs.

A2b is found in the Daschund breed.
