Full List of Tested Traits

Altitude Adaptation - Gene: EPAS1

This gene causes dogs to be especially tolerant of low-oxygen environments, such as those found at high elevations.

Appetite - Gene: POMC

This gene influences food motivation and eating behavior.

Back Muscling & Bulk (Large Breed) - Gene: ACSL4

This gene can cause heavy muscling along the back and trunk in large-breed dogs.

Body Pattern - Gene: Agouti Signalling Protein (ASIP)

This gene is responsible for causing different coat patterns.

Brown or Black Pigment - Gene: Tyrosinase Related Protein 1 (TYRP1)

This gene determines whether a dog produces brown or black pigments.

Chondrodysplasia (Leg Length) - Gene: Chr. 18 FGF4 Retrogene

Coat Texture - Gene: KRT71

This gene contributes to whether a dog’s coat is curly, wavy, or straight.

Color Dilution - Gene: Melanophilin (MLPH)

This gene determines whether a dog has lighter “diluted” pigment.

Dark brown pigment - Gene: HPS3

This gene determines if a dog produces dark brown pigment instead of black in both their hair and skin.

Dark or Light Fur - Gene: Melanocortin Receptor 1 (MC1R)

This gene determines if a dog can produce dark hairs and can give a dog a black “mask” or “widow’s peak.”

Eye Color - Gene: ALX4

This gene is associated with blue eyes in dogs.

Facial Fur Pattern - Gene: Melanocortin Receptor 1 (MC1R)

This gene determines if a dog can produce dark hairs and can give a dog a black “mask” or “widow’s peak.”

Furnishings - Gene: RSPO2

This gene is responsible for the mustache, beard, and eyebrows characteristic of some breeds.

Hairlessness (Terrier type) - Gene: SGK3

This gene is responsible for hairlessness in the American Hairless Terrier.

Hairlessness (Xolo type) - Gene: FOXI3

This gene can cause hairlessness over most of the body and affect tooth shape and number.

Harlequin - Gene: PSMB

This gene determines whether a dog will have harlequin patterning, or a white coat with patches of darker pigment.

Hidden Patterning - Gene: Canine Beta-Defensin 103 (CBD103)

This gene helps determine whether a dog has a black coat.

Hind Dew Claws - Gene: LMBR1

This gene can result in extra, nonfunctional digits located midway between a dog's paw and ankle.

Immune Response 1 - Gene: DRB1

This gene is related to diversity in the Major Histocompatibility Complex (MHC II).

Immune Response 2 - Gene: DQA1 and DQB1

These genes are related to diversity in the Major Histocompatibility Complex (MHC II).

Inbreeding - COI

Our genetic COI measures how closely related a dog’s parents were.

Merle - Gene: PMEL

This gene is responsible for a mottled or patchy coat color in some dogs.

Muzzle Length - Gene: BMP3

This gene affects muzzle length.

Oculocutaneous Albinism Type 2 - Gene: SLC45A2

This gene can cause severely reduced or absent pigment in the eyes, skin, and hair.

Panda White Spotting - Gene: KIT

Panda White Spotting originated in a line of German Shepherd Dogs and causes a mostly symmetrical white spotting of the head and/or body. This is a dominant variant of the KIT gene, which has a role in pigmentation.

Red Pigment Intensity

These loci influence the concentration of red pigment in a dog’s coat.

Roan - Gene: USH2A

This gene, along with the S Locus, regulates whether a dog will have roaning.

Saddle Tan - Gene: RALY

This gene causes the black hairs to recede into a "saddle" shape on a dog’s back.

Shedding - Gene: MC5R

This gene affects how much a dog sheds.

Tail Length - Gene: T

This gene can cause a short bobtail.

White Spotting - Gene: MITF

This gene is responsible for most of the white spotting observed in dogs.
