What is Embark?

Squirrell

Mixed Breed

“Squirrell is 100lbs if attitude in a 20lb body! Very Alpha. She acts like a great wolf huntress, throws her head back when she howls and barks, and is super (vocally) protective. She also runs SUPER fast and very low to the ground. Somewhat of a loner in my pack. Will not eat or potty if being watched, and ONLY loves meaty treats.”

Coat Color

A number of genes are known to affect coat color in dogs, and they all interact. In some cases, other genetic effects may also influence color and pattern.

Body Size

Body size is a complex trait that is affected by both genetic and environmental variation. Our genetic analysis includes genes that, together, explain over 80% of the variation in dog body size. It does not account for runting or stunting; nor does it account for the interactions between various genes both known and unknown.

Maternal Haplotype

Paternal Haplotype

Through Squirrell’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

Squirrell’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.

B6/8/67

Squirrell’s Haplotype

Part of the large B1 haplogroup, this common haplotype occurs in village dogs from South America to the Middle East, all the way down to the French Polynesian Islands. Among the 12 breed dogs we have seen it in, it occurs most frequently among German Shepherd Dogs, English Springer Spaniels, and Havanese.

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

Paternal Haplotype

This 'Paternal Haplotype' tab is for deep ancestral lineage going back thousands of years.

For recent ancestry—"What breeds did my dog inherit from her mom and dad?"—please refer to the Breed, Family Tree, or Summary tab.

The Paternal Haplotype refers to a dog’s deep ancestral lineage stretching back thousands of years, before there were any distinct breeds of dog. We determine the Paternal Haplotype 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 Squirrell is a female (XX) dog, she has no Y-chromosome for us to analyze and determine a paternal haplotype.
