![]() 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.The following five patterns are all types of tabby markings. The best way to determine if a cat is a tabby is to study its coat pattern. Different Types Of Tabby Cats Markings And Coat Patterns Sometimes coat markings are faint or similar in color to the rest of the hair, but they’re there if you look close enough. Sometimes with other colored cats, you can only see the tabby markings if the light hits the fur at the right angle. This is because the gene for those coat colors also makes tabby markings visible.Īlso Read: All About The Majestic Orange Tabby Cats For example, you’ll never find an orange or cream-colored cat that is not a tabby. Without pulling out the punnet squares we learned in high school biology, there are other ways to determine if a cat is a tabby without taking a close look at the coat patterns. Besides the classic “M” marking, tabbies also have thin stripes on their faces and markings around their eyes. Legend says this letter stands for Mau, the ancient Egyptian word for “cat.” Others claim the “M” stands for Mohammed or the Virgin Mary. All tabbies have a distinctive “M” on their forehead. You can start identifying a tabby by looking at the cat’s face. You can’t call every cat a tabby cat, but it is the most common coat pattern among domestic cat breeds (including mixed breeds). Some cats have other genes that mask the tabby characteristics. This doesn’t, however, make every cat a tabby cat. If you want to get technical, all cats possess the gene for tabby markings. Identifying a tabby starts with understanding what a tabby actually is and knowing the different ways those genes affect coat patterns. The term “tabby,” however, refers to a cat’s coat pattern and has nothing to do with breed. You can also breed cats to have traditional tabby characteristics. It’s true that many tabby cats can look alike. It’s a common mistake, however, to use this word to identify a specific cat breed or cats in general. When someone says the word “tabby,” it’s clear they’re talking about cats.
