Best answer to the question Ā«Is the albino mutation recessive in cats?Ā»
The albino mutation is recessive to the Burmese (cb) and Siamese (cs) mutations following the allelic series C>cb=cs>ca. Note: The albino mutation is very rare in cats. Among 9229 cats tested by the VGL, only 4 (2 Tonkinese and 2 Siamese) were positive for this mutation.
Frequently Asked Questions
Those who are looking for an answer to the question Ā«Is the albino mutation recessive in cats?Ā» often ask the following questions:
š» What is albinism in cats?
Feline albinism is a rare inherited condition characterized by a lack of pigment resulting in cats with a white coat and blue eyes. Two mutations in the Tyrosinase ( TYR) gene produce the Burmese (sepia), Siamese, and mink colorpoint coat and eye color phenotypes in cats.
š» What causes Siamese cats to be albino?
Two mutations in the Tyrosinase ( TYR) gene produce the Burmese (sepia), Siamese, and mink colorpoint coat and eye color phenotypes in cats. A rare mutation in TYR (c.936delC) causes a shortened form of the TYR protein and produces an albino phenotype of a white coat with blue eyes.
š» Are albino cats different from white cats?
The feline albino mutation is a rare mutation that produces a white coat with blue eyes, and is recessive to the sepia and Siamese mutations. Albino cats are white with pink eyes, whereas all white cats are not necessarily albino. The distinction is in their DNA and how pigment is produced.

We've handpicked 27 related questions for you, similar to Ā«Is the albino mutation recessive in cats?Ā» so you can surely find the answer!
How are albino cats recognized?Albino cats are recognized by the white coat and blue eyes. The albino mutation causes a premature stop codon in the tyrosinase gene. The mutation is recessive and the albino cats are homozygous for the mutation. Since the tyrosinase gene is essential in multiple biochemical pathways, albino cats are usually deaf.
What is the albino phenotype of Tyr?
A rare mutation in TYR (c.936delC) causes a shortened form of the TYR protein and produces an albino phenotype of a white coat with blue eyes. The albino mutation is recessive to the Burmese (cb) and Siamese (cs) mutations following the allelic series C>cb=cs>ca.

How Does an Albino Cat Look Different From a White Cat?
Why do albino cats have pink eyes?
āThe albino allele is inherited as a recessive to the full color ( C) and by implication to all other albino alleles.ā The pink color of the albino catās eyes is a result of light āpassing through the translucent tissue in the eye structuresā.

What is the rarest cat color?
1. Albino Cats. The albino cat is the rarest of all coat types. Two recessive alleles in the C gene cause complete albinism, and it is extremely rare for cats to get both.
What is the rarest color of cat?
1. Albino Cats. The albino cat is the rarest of all coat types. Two recessive alleles in the C gene cause complete albinism, and it is extremely rare for cats to get both.
Is the Japanese Bobtail a dominant or recessive trait?
Some say the most famous bobtailed cat of Asia, the Japanese Bobtail mated with other Asian cats and spread the gene far and wide. The genetic mutation causing the short tail of the Japanese Bobtail is recessive (but some believe it is a ādominant mutation with incomplete penetranceā).
What does it mean to see a solid white cat?
This is what causes a cat to be solid white when the dominant allele is present; if there is a recessive allele, the color of the coat will appear instead of the white. For a cat which is albino, this will come as a direct result of a mutation of the TYR gene.
Can a kitten be albino?
The albino gene is recessive, meaning that a kitten will only inherit it from its parents to be albino. A cat can either have complete albinism or incomplete albinism. Incomplete albinism is more complex and also more common. The most exciting part about cats with incomplete albinism is that they are sensitive to temperature!
Is the TYR gene dominant or recessive in cats?
Taken together, our results suggest that the TYR gene corresponds to the colour locus in cats and its alleles, from dominant to recessive, are as follows: C (full colour) > c (b) (burmese) > or = c (s) (siamese) > c (albino). Pedigree segregating for complete andā¦

Is there such a thing as a pink eyed albino cat?
This type of albinism is caused by the allele c which is recessive to C, Cs, Cb, and ca. A cat needs to be c/c to be a pink-eyed albino. It seems that this albinism allele is present in the Oriental and Siamese population, and it is very rare. This color is often called recessive white by Oriental and Siamese cat breeders.
What are the advantages and disadvantages of outbreeding?
Outbreeding increases the genetic variation in progeny genomes. There is a high probability of continuing deleterious recessive mutation in inbreeding progenies. Outbreeding reduces the chance of expression of deleterious recessive mutations in offsprings.
Are Siamese cats albino?
All Siamese cats have a gene that makes them partially albino. They are white cats, and that's how they're born. However, this gene has a mutation which affects enzymes that control the color of the fur, and those enzymes don't work in warm temperatures.
Is Burmese head defect dominant or recessive?
Burmese head defect is inherited as an autosomal recessive trait, but it is linked with brachycephaly, which causes shortened face and more rounded skull. Cats that inherit only one copy of the genetic mutation (ie from only one parent) will have a brachycephalic head shape.
What happens if a cat has a mutation?
Cat mutations generally show up randomly as recessive genes come out and different breeds of cats are mixed. If a mutation occurs which significantly alters the anatomy of the cat, there is usually great debate on whether it should be allowed to die out or if the mutation is harmless enough to encourage breeding.
What causes Siamese cats to be albino?
Two mutations in the Tyrosinase ( TYR) gene produce the Burmese (sepia), Siamese, and mink colorpoint coat and eye color phenotypes in cats. A rare mutation in TYR (c.936delC) causes a shortened form of the TYR protein and produces an albino phenotype of a white coat with blue eyes.
What differentiates an albino cat from the other Furry Ones?
Letās see what differentiates them from the other furry ones. An albino cat is a feline that has āsufferedā a genetic mutation. They lack melanin, a pigment found in some cells that produces the coloration of skin, hair and eyes. So in addition to having the white coat you will also see that its skin is pink, without spots.
What kind of albino cat has pink eyes?
Pink-eyed albinos: these cats are entirely white, with blue eyes that have some reddish hint. This type of albinism is caused by the allele c which is recessive to C, Cs, Cb, and ca. A cat needs to be c/c to be a pink-eyed albino. It seems that this albinism allele is present in the Oriental and Siamese population, and it is very rare.
What is an albino tabby cat?
Mean while have a look at the tabby cat from us. An albino cat is a feline that has āundergoneā a genetic mutation. They lack melanin, a pigment found in some cells that produce the coloration of skin, hair, and eyes. So in addition to having the white coat you will also see that its skin is pink without spots see you cat age from cat years.
What kind of mutation makes a Siamese cat a sepia?
Two mutations in the Tyrosinase (TYR) gene produce the Burmese (sepia), Siamese, and mink colorpoint coat and eye color phenotypes in cats. A rare mutation in TYR (c.936delC) causes a shortened form of the TYR protein and produces an albino phenotype of a white coat with blue eyes.
What causes Burmese head defects?
Burmese head defect is an autosomal recessive genetic mutation (Lyons et al 2016), meaning that cats require two copies of the mutated gene (homozygous), one from each parent, to be affected with the severe craniofacial malformations.
What causes Siamese cats to be different colors?
A recessive gene called Himalayan or pointed gene is responsible for the appearance of the Siamese cat breedās color. When a kitten is born, heās considered partially albino. The genetic code then gradually mutates and controls how the enzymes that are in control of the coat color works.
What is a blue-eyed albino cat?
This type of albinism is caused by the allele ca which is recessive to C, Cs, and Cb. So, a cat needs to be ca/ca to be a blue-eyed albino. These cats should not be mistaken for white cats with blue eyes which I will talk of in another article. "Classic" white cats have a dominant white gene and their eyes are not sensitive to light.
What is the history of the hairless cat breed?
The most well-known hairless cat breed is the sphynx, which originated in Canada in the 1960s. Resulting from a naturally occurring recessive genetic mutation, the sphynx was developed through crossbreeding with shorthair cats to create a healthy, broad gene pool.
Why do some cats have short tails?
In reality, the catās short tail stems from a natural genetic mutation. The trait is recessive; if two cats with short tails mate, their kittens will have them as well. 3. JAPANESE BOBTAILS AREN'T ALWAYS CALICO (AND THEIR EYES DON'T ALWAYS MATCH).
What are the genotypes of a purebred cat?
