hairlessness
A characteristic of certain Holstein calves; they are born without hair on most of their body
offspring ...
The hairlessness, so called, because in fact the mature Sphynx has a very short downy coat which can be felt or seen only with difficulty, but no true eyebrows or whiskers - which is caused by a recessive gene.
The hairlessness (or near hairlessness to be more accurate) is due to a recessive gene mutation. With careful breeding the Sphynx is a strong and robust cat with no inherent genetically based health problems.
Sphynx hairlessness is produced by an of the same that produces the . The Sphynx allele is incompletely dominant over the Devon allele; both are recessive to the wild type.
Sphynx hairlessness is produced by an allele of the same gene that produces the Devon Rex, which has only one of the usual two fur coats. The Sphynx allele is incompletely dominant over the Devon allele; both are recessive to the wild type.
The gene for hairlessness has appeared all over the world, but the first formal breeding programme began in Canada in 1966 when a Domestic Shorthair produced a hairless kitten; it took a while for a name to be fixed on, but one name, ...
All but one coat usually results in hairlessness. The Donskoy carries a dominant hair loss gene that causes their birth coat to fall out if they have one. Their coats include Rubber Bald, Flocked, Velour and Brush.
This is mutation cat breed whose characteristic hairlessness is caused by a dominant gene.
Peterbald or Russian Peterbald - this is a hybrid cat breed, created by crossing a Donskoy or Don Hairless with Siamese cats and Oriental cats.
They are unrelated to the Sphynx, as the gene that causes the hairlessness is different.
The Peterbald is a graceful, muscular, foreign-bodied cat with long legs and fine to medium boning.
Some purebred cat registries have refused to recognize the Sphynx breed, on the grounds that its hairlessness is a genetic abnormality which may be potentially harmful to the cats' health, longevity and well-being.
The most distinctive feature of this cat is its appearance of hairlessness. The Sphynx is of medium size and body conformation with surprising weight for its size.
The Sphynx is not the first instance of hairlessness in domestic cats. 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 Sphynx is distinguished by its hairlessness, though actually it is covered by a soft down. Because the Sphynx lacks hair to absorb natural skin oils, it must be bathed frequently.
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...
The Peterbald is the newest hairless breed. They are descended from the Russian Don Hairless breed with outcrosses to Oriental and Siamese cats. They are unrelated to the Sphynx, as the gene that causes the hairlessness is different.
This indicated that the mutation gene responsible for hairlessness is recessive, at least among cats with normal length coats. Other experiments were done by crossing Traditional Sphynx to Devon Rex.
