The variability of the wideband can be described as Wb, Wb+ and Wb++ to describe cats with normal, intermediate and greater degrees of Wide Banding. It is difficult to produce and is required for both parents to carry the gene (Wb). The effect of the genes increases the width of the bands of ticking on the hairs it distorts and effectively breaks down the tabby pattern. When a smoke-patterned cat is still, the coat pattern may appear solid, but when the cat is moving or you pet him, you can see the white undercoat.Ĭhinchillas are derived from the Tabby, where the colour is restricted to the upper portion of the hair, the mutation genes responsible for this are ‘Wide-band’ (Wb) genes. In the smoke pattern, half of the guard hair farthest from the cat’s body displays the colour. With the shaded pattern, a quarter of the guard hair farthest from the cat’s body exhibits the colour. In Chinchillas, only the very tip of the guard hair, or outer coat, is coloured, it gives a delightful shimmer to the coat. There are three types which include chinchilla, shaded and smoke, each distinguished by the extent of the shading on individual hairs. In the Silver & Golden Cats, the 'type' is characterized by colour at the tips of the hair. The hierarchical order: Ticked (Ta) > Spotted (T) > Classic (tb) The Agouti coat colour genome will tell you if your cat has the Tabby pattern or if they would produce solid kittens. It is worth knowing that the ticked tabby is on a different locus from classic/mackerel/spotted tabby. It is difficult to produce and is required for both parents to carry the same gene. The Standard allows a wide range in the degree of coloured markings. The Standard for the British Shaded recognises these different types of markings: Ticked (Ta), Spotted (T), & Classic (tb) and the recessive tb allele produces the classic, or blotched, tabby. The dominant allele, T, produces the mackerel or striped tabby coat the Ta allele produces an all-agouti tabby, like the Black Golden Ticked. If a cat inherited the A allele, the T gene determines what kind of tabby pattern will be produced. If a cat has 2 copies of the non-Agouti mutation they will be solid in colour. The dominant allele A gene controls the coat’s “ticking,” or Tabby banding of colours on a cat’s fur. The recessive allele (non-Agouti mutation), a, makes the cat’s fur a solid colour from tip to root. In which each hair displays alternating bands of dark and light pigmentation. The agouti (A) is a gene that affects the distribution of the natural pigment, melanin (eumelanin and phaeomelanin), in the hair of the cat. Purely focusing on our lines, I've tried to explain it simply and therefore not covering all the variations in the breed. Over time I collected some great source material to help understand what makes outstanding colours and markings in our cats. In the beginning I had not appreciated how complex cat colours and markings actually are. I am often asked how these amazing colours are created.
