What is the white spotting gene?

Dominant white (DW) and white spotting (Ws) are found across many breeds of cats and result from the insertion of a common “feline endogenous retrovirus” in the KIT gene. Dominant white is distinct from albinism (ca) which results from a mutation in a different gene that has no known impact on hearing.

Is white a recessive gene in cats?

The dominant white gene (WD) encodes complete white coloration by disrupting replication and migration of melanocytes into the skin. It is also associated with blue eyes and deafness. Because it’s inherited in a dominant manner, one variant is enough for the trait to be expressed.

Can a cat with the white spotting gene show no white spots?

In fact, the white gene hides the effect of any other color gene: it’s epistatic! The “ws” allele is responsible for white spots and is codominant with the allele w for a cat without white spots. So, if a cat is W/W, W/ws, or W/w, it will be entirely white, no matter all the other color genes.

What is dominant white in cats?

The dominant white gene is associated with developmental defects where melanocytes fail to migrate to the skin during embryologic development. The underlying colour will show up in any offspring that don’t inherit the Dominant white allele. The white spotting gene (S) creates white markings on a solid or patterned cat.

Do dominant white cats always have white kittens?

Only the immediate parents determine the color/pattern of a kitten. The color/patterns found in the pedigree of a kitten will NOT always directly affect the color/pattern of the kitten. A dominant characteristic (all dominant colors and patterns such as shaded, smoke, white, tabby, bi-color, etc.)

Is white a dominant gene?

White is a widespread coat color among domestic pig breeds and is controlled by an autosomal dominant gene I.

Are most white cats female?

Torties are almost always female. Pure white cats exist, but the most common way to see white on a cat is in a bicolor pattern—patches of white with another color. They are almost always female. Below you’ll find the most common base coat colors.

How do white cats stay so white?

The team found that cats have thousands of hollow rigid spine-like structures on their tongue which help them wick saliva (moisture) deep into the fur and clean it. Besides helping the tongue deliver saliva into the fur, papillae also act as a brush that helps in untangling and removing broken hairs from the skin.

Which race has the least genetic diversity?

Native Americans had the least genetic diversity of all, indicating that part of the world was settled last.

Which genes will my baby inherit?

What color eyes will your baby have? There are usually two versions for each gene: one strong (in genetics it’s called dominant) and a weak one (called recessive). Your baby inherits genes from both parents. Some of them will be dominant and some recessive.

What is the genotype of a ragdoll cat?

Pointed traditional Ragdoll cats are produced by parents with the genotype of cscs. So, if both Ragdoll parents are cscs, then 100% of the kittens will be traditional. A traditional cscs cat bred to a cbcs mink Ragdoll will produce 50% traditional kittens.

How do you determine the origin of a ragdoll?

One needs only to LOOK AT THE LINES IN A PEDIGREE to determine the origin of a Ragdoll—whether the Ragdoll in question is a descendant of the four Original Ragdolls OR outcrossed to produce the Mink, Solid, or Sepia.

What is the genotype of a white-spotted cat?

Cats with N/Ws genotype will have white spotting. They will transmit this white spotting variant to 50% of their offspring, and those offspring are expected to be white-spotted. Cats with Ws/Ws genotype will have white spotting.

Why are Ragdoll eyes not green like Siamese?

Traditional Ragdolls carry the Siamese gene mutation, so they do not have enough pigment to achieve green to the rich copper colored eyes of their counterparts.
