What is Cornish Rex mix of?

What mutation defines the Cornish Rex breed?

In 2013, researchers identified the mutation that defines the Cornish Rex breed. Genome-wide analyses were performed in the Cornish Rex breed and in 11 phenotypically diverse breeds and two random bred populations. A gene on chromosome A1, the lysophosphatidic acid receptor 6 (LPAR6), was identified to have a 4 base pair deletion.

What causes Cornish Rex fur to curl?

The curl in Cornish Rex fur is caused by a different mutation and gene than that of the Devon Rex. The breed originated in Cornwall, Great Britain. The coat of a Cornish Rex is extremely fine and sometimes curly.

What is the Rex mutation?

The Rex mutation is a variable that exists in mammals, which creates lovely, plush curls and waves. Cats are just one of the several animals that have this coat structure. You can also see Rex coats showing up in rabbits, rats, horses, and even dogs! Genetically, Rex coats can produce several colors, textures, and curl types.

Are there any breeds of Rex cats that are extinct?

A number of experimental breeds have been developed from the main 4 rex breeds, such as the German-bred Pudelkatze (Poodle Cat), now believed to be extinct. The Tennessee Rex is a natural mutation breed of cat dating back to 2004.

How did the Rex cat get its name?

The name Rex was taken from the Rabbit Fancy because the first rex cat breed to be developed, the Cornish Rex, has a coat similar to that of a rex rabbit, in that it comprises only the undercoat with no topcoat or guard hairs. 1930s: Karakul Cat. Occurred in the USA and was recorded as a novelty, but not developed as a breed.

Why are coat gene mutations in cats going extinct?

These genes were discovered in random-bred cats and selected for. Some of the genes are in danger of going extinct because the cats are not sold beyond the region where the mutation originated or there is simply not enough demand for cats expressing the mutation. In many breeds, coat gene mutations are unwelcome.

Where did the Rex Rex come from?

Rexes appeared in America, Germany and the UK, where one breeder caused consternation by calling them “Maine Waves”. Two UK breeders did test mating which indicated that this was probably a new rex mutation and that it was recessive.

Why does my Rex cat have hair on his head?

Some rex cats are prone to temporary hairlessness, known as baldness, during moulting. Here are a few other genes resulting in unusual fur: The Wh gene (dominant, possibly incomplete) results in Wirehair cats. They have bent or crooked hair producing springy, crinkled fur.

Are Oregon Rex cats extinct?

Unfortunately, the Oregon Rex cat breed is no longer produced, meaning that for all intents and purposes, Oregon Rex cats are extinct. The closest relatives of the Oregon Rex are Selkirk Rex cats, which originate in Montana rather than Oregon. Oregon Rex Cats had no special nutritional needs.

What causes a cat to get a rex coat?

The rex coat itself is caused by a spontaneously occurring genetic mutation that is then selectively bred into subsequent generations of the cats.

What is a “Rex” cat?

The term “rex” refers to a genetic mutation that leads to cats carrying the gene being born with a distinctive curly haired or wavy coat.

What are some examples of coat gene mutations?

In many breeds, coat gene mutations are unwelcome. An example is the rex allele which appeared in Maine Coons in the early 1990s. Rexes appeared in America, Germany and the UK, where one breeder caused consternation by calling them “Maine Waves”.

What are the most common mutations in cats?

Mutations abound in the cat kind, and over 250 have been documented in domestic cats, including taillessness in Manx cats, congenital deafness of white cats, the American Ringtail’s curly/twisted tail syndrome, and the Japanese bobtail, split-foot syndrome (syndactyly). Over 250 mutations have been documented in domestic cats.

What kind of cat is an Oregon Rex?

The Oregon Rex was one of several breeds of Rex cats which in the mid-20th-century occurred from spontaneous genetic mutation. After its acknowledgment as a separate breed, it enjoyed a short time of popularity among cat breeders in the United States.

What is the origin of the Selkirk Rex cat?

According to the CFA, the Devon Rex cats and Cornish Rex cats originated in the 1950s in Devonshire, England, when individual cats each gave birth to a curly-furred kitten. Selkirk Rex cats, though, come from an entirely different line of curly kitties.

Why do Sphynx cats like to snuggle?

Although Sphynx cats do have a natural body temperature which is actually 4 degrees warmer than average cat temperatures, snuggling is a means for them to stay warm anytime they feel the need to.

Why did the Oregon Rex cat go extinct?

In the process of breeding, all the Rex cat varieties were crossed with each other. Because all these breeds differed genetically from each other, the Oregon breed ceased to exist as a stand-alone breed and soon became extinct by the beginning of the seventies.

Where did the Oregon Rex breed come from?

At the same time, the first Cornish Rex were imported to the U. S. from Great Britain, and were soon interbred with the developing Oregon Rex breed. Breeders from Oregon then established a purebred Oregon Rex which soon became one of America’s most popular Rex breeds.

Which genetic mutations determine the phenotype of long-haired domestic cats?

Four independent mutations in the feline fibroblast growth factor 5 gene determine the long-haired phenotype in domestic cats. J Hered. 2007;98:555–66.
