Recessive inheritance
If both genes of a gene pair for a specific trait must be equal that this trait can be seen in the external appearance of the cat.
Rosettes ...
Recessive: Gene not expressed unless both members of a specific gene pair are recessive.
Red: Cat color.
Red-Lynx Point: Colorpoints that are reddish orange with underlying tabby patterns.
Recessive Gene
Recessive Gene - gene that will pass on a characteristic only if another identical gene appears in the allele

Double Recessive - An individual who is homozygous for two pairs of recessive genes.
Down Hairs - The down hairs are the shortest, finest & closest to the skin. Their purpose is to keep the cat warm.
Recessive silver pointed with white

Recessive silver tabby pointed with white ...
RECESSIVE - An adjective applied to that member of a pair of genes which fails to express itself in the presence of its dominant allele. The term is also applicable to the trait produced by a recessive gene.
The recessive mutation for long hair in felines probably occurred spontaneously centuries ago and was perpetuated through interbreeding in confined, mountainous areas that would limit outcrossing, like the Lake Van region in Turkey.
The recessive gene produces the curl in the tail. This is much more unusual than the aerial tail and is seen in feral and domestic cat populations around Hayward, California, says Beth Gardner, ...
With the mix of recessive genes introduced via likely initial outcrossing, it is not surprising that fluffy, long haired and oddly coloured kittens were said to appear during early breeding programs.
There are no known recessive short tail genes in the Jaguarundi Curl breed. By carefully selecting full-tailed Highland Lynx as outcrosses, the short tailed gene will not be introduced into the breed.
The wavy coat is a recessive gene inherited from both parents. Therefore a straight coated kitten from Classic Cornish Rex parents still possesses the recessive Rex gene.
In order to preserve this recessive mutation, the breeding program combined inbreeding with outcrosses to Siamese, British Shorthairs, and Burmese. In 1967, the Cornish Rex was officially recognized in England. In 1960, Professor E.
Because the shorthaired trait is recessive, the American Longhair still produces shorthaired variants.
Birmans are susceptible to a dermatological condition called congenital hypotrichosis, which is inherited as an autosomal recessive trait in this breed.
The Devon and the Cornish Rex have coats governed by recessive genes. In order for a cat to display a recessive characteristic, the kitten must inherit the gene from both parents.
In considering a dominant with a recessive feature, if both cats show the dominant feature, at the offspring will also show the dominant feature. If both cats display the recessive feature, all the offspring will display the recessive feature.
One theory holds that the Abyssinian bloodline still retains a recessive spotting gene left over from crosses with the Egyptian Mau, dating back to when the Abyssinian and the Mau lived in the same region.
This is the combination of the expression of the silver gene (a dominant), and the gene for solid color (a recessive). Other modifiers account for whether the cat is a referred to as a smoke, a shaded, or a chinchilla.
As the longhair gene is recessive, many have argued that a mating to a longhair must be in their background, but much research into pedigrees and anecdotal evidence has not established that this was the case. A natural mutation is likely.
The short tail is caused by the expression of a recessive gene. Thus, so long as both parents are bobtails, all kittens born to a litter will have bobtails as well.
The Havana Brown is an "engineered" breed, in that the breed was developed by breeding black domestic cats carrying a brown recessive gene with a seal or chocolate point Siamese.
The Balinese was developed from a recessive gene in the Siamese gene pool. This recessive gene was for long hair. These longhaired kittens appeared in purebred Siamese kitten litters in the 1940s.
The recessive longhaired gene was present in the Abyssinian breed for years, probably introduced after World War II when the Aby breed was nearly wiped out in England.
Because hairlessness is a recessive gene, some of the kittens resulting from this union had hair, while others did not.
with the American Curl cat, which mutation was caused by an autosomal dominant gene (only one copy of the gene is necessary for the trait to be expressed) the mutation in the American Wirehair was caused by an incomplete dominant gene (a recessive ...
Since the Burmilla carries a recessive long-haired gene from the Chinchilla ancestry, long-haired kittens appear from time to time. The coat of a long-haired Burmilla is fine and silky, longer at the ruff and with a flowing plume-like tail.
This is a mutation cat breed whose characteristic hairlessness is caused by a recessive gene.
Donskoy, Don Hairless, or Don Sphynx - a hairless cat, but that has a "peach fuzz" type of coat.
Why did a shorthair breed like the Abyssinian ever come to carry a longhair gene, even a recessive one? There is a good deal of speculation. It may be that the gene was introduced when the breed was revived just after WWII.
The pattern is recessive genetically and so rigid requirements must be upheld to maintain and accentuate the proper markings. It is not just a Siamese with white.
It is a simple recessive giving a metallic look to the hair and a softer texture. While unique to the Bengal cat it is not required and should not be a considering factor
Contrast: ...
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.
In humans there is another form of PKD, called autosomal recessive, in which the person must have two genes for PKD for signs to develop.
Albino: A relatively rare, genetically recessive condition resulting in white hair and pink eyes.
Allele: One member of a pair or series of genes that occupy a specific position on a specific chromosome.
Both the A and B forms of hemophilia are x-linked recessive traits, where males bleed excessively and the females carry the trait and pass it on.
offspring were carrying a recessive long haired gene. Two of these cats were mated and finally produced the cat with the longer coat. The name Balinese was picked.
The Semi-Longhaired variety first made an appearance in the mid-1980s, as a consequence of the experimental breeding programme for the Burmilla in the UK. Since the Burmilla carries a recessive long haired gene from the Chinchilla Persian ancestry, ...
The original introduction of the longhaired gene took place in Britain and Abyssinians carrying the recessive gene were exported to Europe, America and Australia and it was in America that systematic breeding of the Somali began.
Not every cat gets "high" from catnip, an herb belonging to the mint family. Whether or not a cat responds to it depends upon a recessive gene: no gene, no joy.
it may look like it came from Venus or Mars—arose in 1950 when a perfectly ordinary cat named Serena had an ordinary litter, except for one fuzzy little "ugly duckling." The wavy coat was confirmed as being a true recessive mutation.
them more stable, and for providing the introduction of a breed feature where an individual cat fails to meet the standard. Outcrossing also has the added benefit of allowing new genes for colours and patterns (particularly those linked to recessive ...
Kirlee was produced by a stray cat and sired by a rex coated feral male and was offered to Stirling-Webb. However, when Kirlee was mated to rex cats from Cornwall only straight haired cats were born showing that two separate recessive rex genes ...
Breeders think that the calico female and the curly-coated male must have been related, since the Devon Rex gene that governs the curly coat is recessive and must be present in both parents to manifest in the offspring.
