Health Summary

warn icon

Sweet Heart Last Chance of Happiness inherited one variant that you should learn more about.

Progressive Retinal Atrophy, prcd

warn icon

Sweet Heart Last Chance of Happiness inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Sweet Heart Last Chance of Happiness’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. Sweet Heart Last Chance of Happiness is unlikely to develop this condition due to this variant because she only has one copy of the variant.

Impact on Breeding

This result is also important if you decide to breed this dog - to produce the healthiest puppies we recommend genetic testing any potential mates for this condition.

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.

B1

Sweet Heart Last Chance of Happiness’s Haplogroup

B1 is the second most common maternal lineage in breeds of European or American origin. It is the female line of the majority of Golden Retrievers, Basset Hounds, and Shih Tzus, and about half of Beagles, Pekingese and Toy Poodles. This lineage is also somewhat common among village dogs that carry distinct ancestry from these breeds. We know this is a result of B1 dogs being common amongst the European dogs that their conquering owners brought around the world, because nowhere on earth is it a very common lineage in village dogs. It even enables us to trace the path of (human) colonization: Because most Bichons are B1 and Bichons are popular in Spanish culture, B1 is now fairly common among village dogs in Latin America.

B1c

Sweet Heart Last Chance of Happiness’s Haplotype

Part of the large B1 haplogroup, we have detected this haplotype in Mexico and Lebanon village dogs. Among the 12 breeds that we have spotted this haplotype in, it occurs most frequently in Border Collies, Australian Shepherd Dogs, and West Highland white Terriers.

The B1 haplogroup can be found in village dogs like the Peruvian Village Dog, pictured above.

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 Sweet Heart Last Chance of Happiness 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 Sweet Heart Last Chance of Happiness is a female (XX) dog, she has no Y-chromosome for us to analyze and determine a paternal haplotype.
