General information
Three recessive mutations in the LVRN gene have been identified in tabby cats, with each mutation altering the cat’s coat pattern and potentially producing a “blotched” pattern. The included tests in this package enable differentiation between the mackerel tabby coat pattern (wild-type) and the blotched/classic tabby coat pattern.
The mackerel tabby, which is one of the most common tabby cat markings, bears a resemblance to zebra stripes with vertical stripes that traverse the entire coat. These stripes are typically narrow and evenly spaced, resembling the shape of a mackerel fish upon closer examination, hence the name.
Conversely, the classic tabby, also known as blotched tabby, exhibits large patches on the coat, usually round or oval in shape, and can appear in varied, random patterns across the coat.
Clinical features
The Mackerel Tabby has slender, curving stripes throughout their body, which may be broken into shorter segments resembling spots, especially on the belly and legs, or continue unbroken. The Classic Tabby pattern is defined by the thick, curving bands of color that often swirl into a bullseye or marbled pattern on the side of the cat’s body.
Additional information
Coat colour is an intricate trait that involves a combination of multiple different genes. Testing for a range of different loci will give the most complete prediction of a cat's coat colour genetics.
