White spotting can take many forms, from a small spot of white to the mostly-white pattern of the Turkish Van, while epistatic white produces a fully white cat (solid or self white). The KIT gene W locus has the following alleles: [25] [26] [27] W D (or W)=dominant white (solid/self white
In white cats with one blue eye and one eye of a different color (odd-eyed cats), deafness is more likely to affect the ear on the blue-eyed side. [1] Approximately 50% of white cats have one or two blue eyes. [5] According to the ASPCA Complete Guide to Cats, "17 to 20 percent of white cats with non-blue eyes are deaf; 40 percent of "odd-eyed ...
The white coat of the Foreign White is induced by the W gene, the "dominant white". This gene favors the appearance of deafness in white cats with blue eyes. This breeding constraint leads Foreign White breeders to systematically cross their subjects with Siamese cats, and to avoid reproductions with the red colors and the tabby pattern.
Solid-white Turkish Angoras carry the epistatic (masking) white colour (W) dominant gene associated with white fur, blue eyes, and often deafness. All-white cats of Turkish Van stock may share this gene. All three types of cat may exhibit eye colours that are amber, blue or odd. Deafness is principally associated with white cats having two blue ...
Tortoiseshell cats have particolored coats with patches of various shades of orange, red, grey, and black, and sometimes white. The size of the patches can vary from a fine speckled pattern to large areas of color. Typically, the more white a cat has, the more solid the patches of color.
This Thoroughbred stallion (W2/+) has one form of dominant white.His skin, hooves, and coat lack pigment cells, giving him a pink-skinned white coat. Dominant white (W) [1] [2] is a group of genetically related coat color alleles on the KIT gene of the horse, best known for producing an all-white coat, but also able to produce various forms of white spotting, as well as bold white markings.
Cat with Waardenburg syndrome. Waardenburg syndrome type 2A (with a mutation in MITF) has been found in dogs, Fleckvieh cattle, minks, mice and a golden hamster. [51] Degeneration of the cochlea and saccule, as seen in Waardenburg syndrome, has also been found in deaf white cats, Dalmatians and other dog breeds, white minks and mice. [52]
Mutations in this gene also cause white spotting. [9] Since a large variety of coat patterns exist within the various cat breeds, the cat is a qualified candidate animal to study the coat genetics of hair growth and coloration. [10] Several genes interact to produce cats' hair colors and coat
