American Bully

The American Bully may look intimidating with its muscular build, but these dogs are bred to be the ideal family or companion dog. This breed is notable for coming in several different size and type varieties, so there's a lot of diversity in their appearance. They're a newer breed, originating in the 80s and 90s in the United States.

Health Summary

warn icon

Tessa inherited one variant that you should learn more about.

Progressive Retinal Atrophy, crd4/cord1

warn icon

Tessa inherited both copies of the variant we tested

What does this result mean?

We do not know whether this increases the risk that Tessa will develop this disease.

Scientific Basis

Research studies for this variant have been based on dogs of other breeds. Not enough dogs with the breeds in Tessa have been studied to know whether or not this variant will increase Tessa’s risk of developing this disease.

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

A1b

Tessa’s Haplogroup

This female lineage was very likely one of the original lineages in the wolves that were first domesticated into dogs in Central Asia about 15,000 years ago. Since then, the lineage has been very successful and travelled the globe! Dogs from this group are found in ancient Bronze Age fossils in the Middle East and southern Europe. By the end of the Bronze Age, it became exceedingly common in Europe. These dogs later became many of the dogs that started some of today's most popular breeds, like German Shepherds, Pugs, Whippets, English Sheepdogs and Miniature Schnauzers. During the period of European colonization, the lineage became even more widespread as European dogs followed their owners to far-flung places like South America and Oceania. It's now found in many popular breeds as well as village dogs across the world!

Tessa’s Haplotype

Part of the A1b haplogroup, this haplotype occurs most frequently in German Shepherd Dogs, Poodles, and Shiloh Shepherds.

A1b is the most common haplogroup found in German Shepherds.

The Paternal Haplotype reveals a dog’s deep ancestral lineage, stretching back thousands of years to the original domestication of dogs.

Are you looking for information on the breeds that Tessa inherited from her mom and dad? Check out her breed breakdown and family tree.

Paternal Haplotype is determined by looking at a dog’s Y-chromosome—but not all dogs have Y-chromosomes!

Why can’t we show Paternal Haplotype results for female dogs?

All dogs have two sex chromosomes. Female dogs have two X-chromosomes (XX) and male dogs have one X-chromosome and one Y-chromosome (XY). When having offspring, female (XX) dogs always pass an X-chromosome to their puppy. Male (XY) dogs can pass either an X or a Y-chromosome—if the puppy receives an X-chromosome from its father then it will be a female (XX) puppy and if it receives a Y-chromosome then it will be a male (XY) puppy. As you can see, Y-chromosomes are passed down from a male dog only to its male offspring.

Since Tessa is a female (XX) dog, she has no Y-chromosome for us to analyze and determine a paternal haplotype.
