Welsh Sheepdog

Intensity Dilution

The intensity coat color gene variant causes an extreme dilution of phaeomelanin (red or yellow pigment), resulting in a cream to white coat in dogs.

Parentage/Genetic Marker Report

This DNA-based parentage test uses microsatellite marker analysis to compare the DNA profile of an offspring to the profiles of possible parents.

Progressive Rod-Cone Degeneration (PRA-prcd)

Progressive rod-cone degeneration (PRCD) is an inherited form of late-onset progressive retinal atrophy (PRA) that has been identified in many dog breeds.

Dog Coat Color - Basic Panel (All breeds)

This basic dog coat color panel bundles together several genetic tests for coat color that are applicable to all breeds.

Furnishings and Improper Coat

A dominant variant of the R-spondin-2 gene produces the longer mustache and eyebrows seen in wire-haired dogs and other breeds.

Curl

A variant in the Keratin-71 gene is associated with curly hair in dogs. Dogs with this curl variant have curly coats or wavy coats depending on how many copies of the variant they possess.

Coat Length

Five recessive variants in the fibroblast growth factor-5 (FGF5) gene are associated with long hair phenotypes in dogs.

Piebald/White Spotting (S Locus)

White spotting patterns that occur in many dog breeds do not have a uniform genetic basis, and the genetics are complex. In piebald/parti/random white spotting, the extent of white pattern expression varies, and markings are often asymmetrical.

Merle

Merle is an incompletely dominant coat color pattern characterized by irregularly shaped patches of diluted pigment and solid color.

Dominant Black (K Locus)

The Dominant Black gene (K Locus) affects pigment switching between eumelanin (black) and phaeomelanin (red or yellow) by interacting with the Agouti and MC1R genes.
