Collie (Scottish-Type)

Scottish-Type Collies, also called Old-Time Scotch Collies, are landrace collies bred first and foremost to excel at their work. Formalized breeds such as the Collie and Shetland Sheepdog were developed from this original landrace population. While these dogs are happy to herd, they’re quite versatile and also enjoy sports such as flyball and agility.

Health Summary

warn icon

Bixby inherited one variant that you should learn more about.

Collie Eye Anomaly

warn icon

Bixby inherited one copy of the variant we tested

What does this result mean?

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

Impact on Breeding

Your dog carries this variant and will pass it on to ~50% of her offspring. You can email breeders@embarkvet.com to discuss with a genetic counselor how the genotype results should be applied to a breeding program.

What is Collie Eye Anomaly?

Named for its high prevalence in Collie dogs, Collie Eye Anomaly (CEA) is more correctly termed choroidal hypoplasia. The choroid anchors the retina to the underlying structures and supplies it with oxygen and nourishment. CEA is a developmental disease of the choroid.

Through Bixby’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.

B1

Rosewyn's Bixby Creek Bridge’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

Rosewyn's Bixby Creek Bridge’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 Bixby inherited from her mom and dad? Check out her breed breakdown.

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