Spontaneous mutation: Genetic accident that permanently alters certain genetic characteristics.
Spotting: White areas in the coat.
Spotting factor: Gene causing white spotting in the catıs coat.
The spontaneous mutation that created the curly-coated Cornish Rex occured twice: In Germany in 1946 and England in 1950.
A spontaneous mutation in ear conformation was discovered in a cat named Shulamith in California in 1981. Selective breeding demonstrated that this ear conformation is a dominant trait, and active breeding to create the American Curl began in 1983.
The Balinese was a spontaneous mutation in Siamese litters in the U.S. in the 1950s.
The Selkirk Rex is the result of a dominant, spontaneous mutation that causes each hair (guard, down and awn) to have a gentle curl giving the coat a soft feel.
The first American Curl cat was seen in Lakewood, CA in 1981 due to a spontaneous mutation and was first shown at a cat show in 1983.
American Wirehair Cats
This breed has hair that is bent or hooked, which makes it's coat feel very dense and harsh.
The American Wirehair is a spontaneous mutation. The coat, which is not only springy, dense, and resilient, but also coarse and hard to the touch, distinguishes the American Wirehair from all other breeds.
For five years, Koehl raised many other curly-coated cats who are the ancestors of the Dalles La Perm breed, the result of a spontaneous mutation by a dominant gene. T.I.C.A. recognized the breed and published a standard in 1996.
The Traditional American Wirehair is a natural, spontaneous mutation based from the Traditional American Shorthair that happened in the U.S.A.
It began as a spontaneous mutation in a litter of upstate New York farm cats in 1966. A spontaneous mutation is an uncommon, although not rare, happening.
The folded-ear is produced by an incomplete dominant gene and is the result of a spontaneous mutation. The ears are usually small, cap-like, and folded forward and down on the head.
Also the true origin of the Balinese is controversial, it is generally accepted that the breed originated from a spontaneous mutation by an incomplete dominant gene of the Siamese cat.
The first LaPerm was born in 1982[1] and was a spontaneous mutation in an otherwise normal litter of kittens. Linda and Richard Koehl owned a cherry farm in The Dalles, Oregon, and had obtained some farm cats to keep the farm clear of mice.
"Peeked" "peke-faced" occur as spontaneous mutations it is said (I don't agree with this). Persian cat breeding no longer uses this mutation, it seems, if it ever existed. Not recognized outside the US (extremely flat faced as for the "extreme") ...
The LaPerm first came into being through a natural, spontaneous mutation in 1982 on the farm of Linda Koehl in The Dalles, Oregon, USA, from a gray tabby barn cat named Speedy.
The American Wirehair is a true American breed, resulting from a spontaneous mutation in a litter of upstate New York farm cats in the mid-to-late 1960s. Both parents were normally-coated.
The unusual characteristic of a hairless cat was probably a naturally spontaneous mutation in the breed.
The very unusual folded-forward ears of this breed originated from what is called a "spontaneous mutation" in a Scottish cat back in the early 1960s. Subsequent line-breeding was successful in reproducing the ear-folds.
The Scottish Fold cat occurred as a spontaneous mutation in farm cats in Scotland. The breed has been established by crosses to British Shorthair and domestic cats in Scotland and England. In America, the outcross is ...
s taillessness is the result of a spontaneous mutation within the Isle?s domestic cat population. Genetically, the Manx and other short-tailed domestic felines are quite different. The Manx?
Like many of the other cat breeds developed in North America in the last decades of the twentieth century, the Sphynx breed owes its existence to a spontaneous mutation. The mutation occurred in a single cat in Toronto in 1966.
General: The American Wirehair is a breed resulting from a spontaneous mutation in the 1960s. The coat, which is not only springy, dense and resilient, but has a coarseness to it, distinguishes the Wirehair from all other breeds.
This natural, spontaneous mutation has been seen in various locations around the world for at least the last ninety-something years, and probably longer.
The American Wirehair, is a spontaneous mutation of the American Shorthair. The only difference is the stiff, wiry coat - every hair is crimped and springy, including the whiskers.
The American Curl is best known for its unique curled ears, which are the result of a spontaneous mutation.
Others believe Persian cats are the result of a spontaneous mutation. It is entirely possible that mating occurred between the European Wildcat, which has a thick longer haired coat, and what we know as the domestic cat.
Mutation Breed - A breed of cat that developed from a spontaneous mutation event. e.g. Cornish Rex, Devon Rex, Sphynx, American Curl etc.
Mutation Breeding - The use of mutagens to develop variants or new breeds.
Since there have been no imports of the Ojus Azules to Australia, this cat would appear to be the result of a spontaneous mutation in the domestic population there. When in the homozygous state, some health issues have resulted.
The Sphynx Cat - Breed History The gene of hairlessness has appeared as a spontaneous mutation several times during the past century, in some well documented occurrences in Europe, Australia and America. The most famous early hairless cats are...
