Health Summary

warn icon

Dora inherited one variant that you should learn more about.

Prekallikrein Deficiency

warn icon

Dora inherited one copy of the variant we tested

What does this result mean?

This variant should not impact Dora’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. Dora is unlikely to develop this condition due to this variant because she only has one copy of the variant.

What is Prekallikrein Deficiency?

Prekallikrein is an enzyme necessary for the activation of certain clotting proteins. Fortunately, this is a benign blood disorder and is not associated with increased bleeding tendencies.

Through Dora’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.

Haplogroup

Haplotype

B1

Dora’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.

B1/13

Dora’s Haplotype

Part of the large B1 haplogroup, this common haplotype occurs in Shih Tzus, Tibetan Spaniels, Maltese, and village dogs throughout the world including Central and South America, South Asia, and the South Pacific.

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