Serval

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

Charcoal Bengals sport an unusual coat marking of a darker face mask and dark thick dorsal stripe ("cape"). This “charcoal” pattern is produced by the combination of a domestic cat non-agouti variant and an Asian Leopard Cat agouti variant.

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.

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