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

Four mutations that produce long-haired coats in domestic cats have been identified in a single gene. Three of the mutations are fairly breed specific, while the fourth is present in all long-haired cat breeds and crossbreds.

Dilute is an autosomal recessive trait that causes clumping and uneven distribution of pigment granules in the hair shaft, producing dilution of all coat colors.

Cats with colored 'points' have genetic mutations associated with temperature-sensitive pigment production. Pigment production is reduced in warmer areas of the body, leading to darker pigmentation in the cat's cooler extremities (paws, ears, etc.)

Cats with brown gene variants have reduced amounts of black pigment and appear brownish in color. 

The agouti signaling protein interacts with the melanocortin 1 receptor to switch between black and red pigments, creating a banding pattern in individual hairs. Mutations in the agouti signaling protein gene (ASIP) prevent this switch from occurring, resulting in hairs of uniform color.

Cornish Rex cats have short, soft, curly coats inherited in an autosomal recessive fashion. This trait is fixed in the breed.

The AB system is the major blood group system in domestic cats. The common blood types are A and B, and a third rare type "AB" is also known. This test detects the known genetic variants that produce B and AB blood types. When these variants are not detected, the cat is likely to have blood type A.

The dominant white and white spotting mutations cause white patterning in cats.
