However, the black coat can also be created by the different gene called B (“brown”), whose recessive versions make a cat’s coat brown (10). Black coat or in another name melanism, arose from the mutation in agouti signalling protein ASIP (11). A cat with two copies of alleles “a/a” is non-agouti, meaning it has a solid coat with no tabby markings – a black cat (3,7). The name of the gene responsible for tabby patterns is agouti or simply “A” gene. The most ancient coat color the cat: “brown” mackerel tabby. Due to optical illusion created by the combination of black and yellow pigments these tabbies appear to be brown (6). A “brown” mackerel tabby could be described as coat with black or greyish stripes on yellow background, sometimes with an orange hue.

There are two pigments that give colors to the cat’s coat: pheomelanin (yellow to orange) and eumelanin (from brown to black). Tabby genes alter the shape and the size of markings, they have no effect on color of the cat (1). No, tabby is not a color.It is a coat pattern. By using science and color genetics we explain why these prevalent beliefs are a complete nonsense. In this article we gathered the most popular and stubborn myths about tabby cats floating in Internet space (and beyond) which simply won’t go away. You may feel tempted to click such a headline – don’t. So many websites provide with “ interesting/fun facts about tabby cats”. But what do we really know about tabby cats?
