Genes are contained within the chromosome which is made up of a double-strand helix containing DNA. If an X sperm fertilises the egg, the offspring will be female (XX), if a Y sperm fertilises the egg, the offspring will be male (XY). All of the female cat’s eggs are X, whereas the male sperm can be X or Y. ![]() 18 of the chromosomes are autosomes, and one pair is the sex chromosomes X and Y. Basic cat geneticsĬats have 19 chromosomes which come in pairs, one from the mother and one from the father. The basic wild-type tabby is a mackerel ( T m) however, two mutations have arisen, the dominant ticked tabby ( T a) and the recessive classic tabby ( t b). Some young cats with solid coat colours will display faint ghost tabby markings until their fur becomes fully pigmented. Even cats with no tabby stripes have tabby genes but do not show the pattern on the fur. All domestic cats were once tabby, mutations lead to some cats appearing solid, bi-colour or pointed. Tabby patterns are common in random-bred cats as well as many pure breeds. a/a (heterozygous recessive) – Non-tabby (solid).A/a (heterozygous dominant) – Tabby (the dominant A will override the recessive a).Three possible outcomes dictate if the coat will be tabby or not, remembering that the cat receives a copy of each gene from the mother and the father. A cat must receive two copies of the recessive ‘ a’ gene (aa) to have a solid coat. The recessive a hides the tabby pattern, to produce a solid (self) coat colour from the root of the hair to the tip. The dominant agouti allele, with the symbol A, will express the tabby pattern. The agouti gene controls whether the tabby markings are expressed or not. This is caused by the transient inhibition of pigment production during, the hair’s growth. The banded background (ground colour) consists of hairs that are more than one colour along the hair shaft and is termed agouti. Tabby refers to a coat pattern in cats that consists of dark swirls, stripes, spots superimposed on a lighter background of ticked (banded fur). What colour is a tabby cat? Tabby occurs in several colours, the most common are brown tabby, silver (grey) and orange tabby.The background hair consists of light and dark bands, intermingled with dark lines, spots or swirls layered on top. What is a tabby cat? Tabby is a coat pattern and not a breed, it consists of four patterns, mackerel, spotted, classic and ticked.Some cat breeds that can have the silver tabby coat are: British shorthair, Russian blue cats, Maine coon, Siamese, and Turkish Angora. ![]() The roots of all the individual hairs on a silver tabby are tipped with black. Silver tabby cats have black markings against a light gray background. ![]() Brown tabbyīrown tabbies have black markings over gray or brown fur.īrown tabbies are one of the most common domestic shorthair cat and longhair cat coat patterns. Tabby cats are often described by combination of the markings color and bast coat color. Tabby cats can have a range of colors with a mix of a darker color for the markings and typically a lighter base for the rest of the fur. Agouti is a fur color that has two or more colored bands running across each hair. The agouti gene is responsible for a cat’s tabby coat pattern. Inherited from their wild ancestors, tabby cats all have a type of coat pattern that has the classic “M” forehead marking, thin pencil lines on the face and around the eyes, banding around the legs and tail, and patterned body that can be one of four patterns: mackerel, ticked, spotted, and classic (also known as marbled). Tabby cats are not a cat breed but a coat fur pattern found on many types of cat breeds as well as cats of mixed breed origin. Tabby cats are the most common type of domestic cats.
