Best answer to the question Ā«Can a white cat have two W genes?Ā»
Since the W gene is dominant, when cat possesses one or two copies of the W allele, it will be white regardless of other coat colour genes it carries. The white cats with the W allele have been linked to deafness. Turkish Van is a famous odd-eyed cat breed.
Frequently Asked Questions
Those who are looking for an answer to the question Ā«Can a white cat have two W genes?Ā» often ask the following questions:
š» Can a dominant white cat give birth to any color?
Dominant white only require one copy of the mutated gene (W) for the cat to have a solid white colour. The white genes, if dominant, tend to mask the genetic effects of the colour points, agouti, and other genetic variations. However, a pregnant white feline may give birth to kittens in any colour without the masking white gene.

š» What is the genotype of a DW/WS cat?
Cats with DW/Ws genotype will be white and may have some degree of hearing impairment. They will transmit a dominant white variant to 50% of their offspring and a white spotting variant to 50% of their offspring.

Why do white cats have the W Gene?Since the W gene is dominant, when cat possesses one or two copies of the W allele, it will be white regardless of other coat colour genes it carries. The white cats with the W allele have been linked to deafness.
What is the W gene in cats?
The W, or white masking gene inhibits the normal production of pigment cells during the embryologic development. Since the W gene is dominant, when cat possesses one or two copies of the W allele, it will be white regardless of other coat colour genes it carries.
Why are white cats with odd or coloured eyes white?
Most white cats with odd or coloured eyes are white due to the white masking gene (W) a dominant gene that is represented with an UPPERCASE āWā ( recessive are shown in lower case ā w ā, which symbolises non-white). The W gene masks the effect of all other colour genes.
Do all white cats have the same gene?
Usually, solid white cats have the dominant white gene (W), and although there are other genes present for fur and eye color, the dominant gene wins out, and there is no pigmentation. Itās very fascinating because the gene is actually masking the real color of the cat!

How many pets did George W Bush have as president?
The two were, however, the subject of a book, Dear Socks, Dear Buddy: Kids' Letters to the First Pets written by then First Lady Hillary Clinton and appeared as cartoons in the kids' section of the first White House website. While George W. Bush was president, he had three dogs and a cat at the White House.
Can two white cats have different Color Kittens?
Even though both cats are white, the dad will pass on genes for the kittens to have different colors, or different markings, but the color will likely be predominantly white. It also depends on whether different colors are accepted in the catās breed.
Why does my cat have white spots on her skin?
The white spotting pattern is due to the insertion of feline endogenous retrovirus in the KIT gene. Anecdotal evidence suggests that are homozygous (ie: have two copies of the W S gene) will display more white than heterozygous cats. A full 7125bp insertion results in white spotting while a partial insertion causes dominant white.
Does having a white cat Mean It will always be white?
Once a cat has inherited the W it conceals whatever color the pet has on its body. However the white cat by W gene can transmit to its offspring and by its true camouflaged color, so having white cats does not guarantee white litters.
Can a non-white cat have blue eyes?
As has already been noted, the gene responsible in this case is known as W, non-white is w. The eyes of a white cat may be blue, non-blue (usually copper or gold) or odd (one of each). Blue-eyed cats are more often deaf than white cats with other coloured eyes.

Are blue eyes cats more likely to be deaf?
Cats who have two blue eyes and who are totally white from the dominant āWā gene are 40 percent more likely to be born deaf. This is not as likely to appear in an albino cat.
Did George W Bush have a cat at the White House?
A cat has not lived at the White House since India, President George W. Bushās cat, in 2009. Willow is one of only a dozen feline inhabitants in the history of 1600 Pennsylvania Avenue, according to the Washington Post. A cat has not lived at the White House since 2009.
Why do cats have odd eyed?
Odd-eyed coloring occurs when the epistatic or major white gene or white spotting genes obstructs melanin granules from accessing an eye during development. The condition rarely occurs in cats without dominant white or white spotting genes.
What is the difference between albino and white cats?
Where white cats have genes that create white fur, often masking other colors in their genetic makeup, albino cats have zero color in their genes and zero melanin.
What does it mean if a cat is WS/W?
As the white spotting allele ws is codominant with the non-white spotting, if a cat is ws/w, it will have white spots but covering a smaller area of its coat when compared to a homozygous ws/ws. Generally, it seems that homozygous cats have more than half of their body covered in white, while heterozygous have less than half.
What is the recessive S allele in humans?
The recessive s allele is actually the normal expression of this gene; it produces no white fur at all. 7. W: White vs. non-white The W gene is known as a masking gene.
Why do white cats only have one copy of their color?
Itās dominant over non-white, and all cats who are white only carry one copy since if they get two, they get reabsorbed by the motherās body as embryos. And since it can be combined with all other genes for colour, a white cat always has something else underneath, something it can pass on. Silver/smoke.
Are white cats prone to deafness?
Mostly white cats and albino cats are not prone to deafness, as they donāt carry the dominant W gene. Cats with mostly white fur carry a different gene, which explains why they are not completely white. As a result, they arenāt susceptible to deafness caused by the dominant W gene. Albinism causes a lack of pigmentation in the skin, fur, and eyes.
What was the name of George W Bush's dog?
Millie was an English springer spaniel that was the first President Bush's family pet. She gave birth to Spotty, who moved into the White House with the seocond President Bush! The commander in chief also had two Scottish terriers named Barney and Miss Beazley, but Spotty was the only pet to live in the White House during two administrations.
Do all cats have the same coat colour?
But each cat will only have two genes at a time. Cats display a huge number of coat colours, but there are only two pigments that determine coat colour. Eumelanin (black) and pheomelanin (red). White is omitted because it is not a colour, but a lack of colour.
Do white cats always have white litters?
However the white cat by W gene can transmit to its offspring and by its true camouflaged color, so having white cats does not guarantee white litters. As a curiosity, it should be noted that some white cats that have the epistatic gene (which hides all colors) are born with some reddish, bluish, black stain.
Why does my cat have white hair and blue eyes?
In cats with the dominant W pigment gene, white skin, hair, and blue eyes occur as a result of melanocyte (pigment-producing cell) suppression. If the W gene acts strongly, it also suppresses melanocytes in the stria vascularis (a component of the cochlea), which leads to strial degeneration and cochlear hair loss in the inner ear.
What are the causes of odd-eyed cats?
Genes leading to all-white or dual colored cats are the reasons behind the cases of odd eyed cat. Odd-eyed coloring occurs when the epistatic or major white gene or white spotting genes obstructs melanin granules from accessing an eye during development. The condition rarely occurs in cats without dominant white or white spotting genes.
Why are there so many white Maine Coons?
The genes that create white are masking genes, so there is actually a color underneath so to speak. A white female can pass on that underlying color or can pass on the masking gene. White Maine Coons are very popular. The Cat Fanciers Associatio n refers to them as āglisteningā!
What does it mean when a cat has a dominant W allele?
That means if the dominant W allele is present, the cat will be white, no matter what the other coat color and pattern alleles say. The recessive w allele produces full expression of any of the other color traits.
