There is one more genetic ingredient when it comes to the color of the coat – the gene locus has to contain two d (recessive) alleles in order to create the muted colors. Then, these two basic colors (black and orange) are muted by the dilute gene, which creates gray and cream colored coats. The mosaic gene means the cat’s coat will contain both black and orange colors. Dilute gene that contains two d alleles at the locus (explained below).There are three key genes that result in the creation of the beautiful dilute calico coat, and those are: We have genetics to thank for the amazing creation of dilute calico cats – it was not an easy task! A unique gene combination is required for a cat to be a dilute calico cat. I find these muted pastel colors absolutely stunning and I would love to one day own a dilute calico cat, just so I can enjoy their pretty colors day after day! The Beauty Of The Dilute Calico Cat – Genetics! White – fawn (diluted cinnamon color) – cream.White – lilac (diluted chocolate color) – cream.White – gray (sometimes referred to as blue) – cream.Chocolate will become lilac, while cinnamon will become fawn.Īs a result, we might observe a diluted calico cat with any of the following three colorations: Like the black fur, the cinnamon and chocolate colors can also be diluted (or muted). It is possible for a cat to have cinnamon or chocolate colored fur instead of the classical black fur. When talking about calicos, it is usually only black, orange, and white colors that are mentioned, but this is not always the case. Potential Coat Colors Of A Dilute Calico Cat You may notice that these cat breeds are the solid color and colorpoint breeds.Ĭat breeds that are exclusively solid colored (such as the Russian blue, for example), or colorpoint cats (such as the Siamese cat) can’t have the calico color and pattern. □Turkish Van There Are Also Cat Breeds That Cannot Have The Dilute Calico CoatĪlthough the list of cat breeds known to have dilute calico members is quite long, there are also quite a few cat breeds that cannot have the dilute calico coat. If you’re wondering which breed of cats you might find wearing the beautiful dilute calico color and pattern, I have a list for you!Ĭat breeds known to have members with this beautiful dilute calico coat: Which Breeds Of Cats Can Be Dilute Calicos? Remember, dilute calico cats are not a distinct cat breed, but rather any cats with a certain coat color and pattern combination. The genetics of muted calicos is pretty interesting, as will be explained further below in the article. That means that instead of black fur they have grey-colored fur and instead of orange fur they have cream-colored fur (also known as strawberry blond). What Is A Dilute Calico Cat?ĭilute calico cats, commonly referred to as muted calico cats, only differ from regular calico cats in the fact that their colors are diluted (or muted). Cats of different breeds can be calico, for example – you can have a calico Maine Coon or a calico Manx cat. The three calico colors are white, black, and orange.Ī common misconception is that calico cats are their own distinct cat breed, but that’s not true. What Is A Calico Cat?Ī calico cat is a cat of any breed, which has a combination of three colors, arranged in intertwining patches. In order to avoid any misunderstandings, let’s first explain what a calico cat and dilute calico cat really are. This results in piebalding, where skin and fur that would normally be pigmented lacks pigmentation, resulting in a white color.13.1 Related Articles: What Is A Dilute Calico Cat? The tri-color, calico (or often called “tortoiseshell-and-white” outside of North America), with the presence of white fur, happens due to a gene unrelated to the X and Y chromosomes. The calico possesses a white spotting gene that the tortie does not. The difference between tortoiseshell cats and calicos is minimal. If the cat only has these two colors, it is known as a tortoiseshell cat. Those two colors then combine on the cat’s fur to create the orange and black patches of fur. In both cases, these cells are replicated and the inactivated chromosome will always stay inactive. Other cells use the chromosome for black fur instead. One cell inactivates the chromosome for black fur resulting in orange fur. However, the offspring receives the chromosome for, for instance, black fur from one parent and orange fur from the other. In the case of calico cats, the same process occurs. Their distinct markings are due to their very specific chromosomal makeup. Today I Found Out host Simon Whistler explains the physiological reason why calico and tortoiseshell cats are predominantly female.
