What does piebald mean in cats?
A bicolor cat or piebald cat is a cat with white fur combined with fur of some other color, for example black or tabby. These range from Turkish Van pattern (color on the crown of the head and the tail only) through to solid color with a throat locket.
What causes Piebalding in cats?
Cats with skin and fur marked by white patches in this way are known as “bicolour” or “piebald”. Piebaldism is also common in a range of domestic and farm animals including dogs, cows and pigs, deer, horses and appears more rarely in humans. It is caused by a mutation in a gene called “KIT”.
Where would you find the O gene in the cat?
the X chromosome
The sex-linked Orange locus, O/o, determines whether a cat will produce eumelanin. In cats with orange fur, phaeomelanin (red pigment) completely replaces eumelanin (black or brown pigment). This gene is located on the X chromosome. The orange allele is O, and is codominant with non-orange, o.
Is piebald spotting dominant or recessive?
Piebald gene is recessive to dominant S (non-white) gene. This means if two piebald carrier dogs are mated ( Ss genotype, non-white phenotype), there is a 25% chance of a piebald cub occurring in the litter, and 50% that the puppy will be a piebald carrier.
Why is it called Piebald?
Etymology. The word “piebald” originates from a combination of “pie,” from “magpie”, and “bald”, meaning “white patch” or spot. The reference is to the distinctive black-and-white plumage of the magpie.
Are GREY cats dilute black?
“The hundreds of colors and patterns displayed in domestic cat coats come about because of modifying factors that include both genes and polygenes, which change these basic two colors,” she says, giving an example of the dilute gene, which changes cat colors from black to blue (commonly called gray) and red to cream.
What color kittens will a tortoiseshell cat have?
BREEDING TORTOISESHELLS Red male and red female only produce red kittens. The combinations which produce tortoiseshell kittens are red male and non-red female, red female and non-red male.
What is piebald spotting in cats?
Piebald Spotting is thought to be a semi-dominant mutation. This means that cats that are SS will display more white than cats that are Ss. Cats that are ss do not carry the Piebald mutation but may still have white caused by other mutations.
Is piebald spotting a dominant or semi dominant mutation?
Piebald Spotting is thought to be a semi-dominant mutation. This means that cats that are SS will display more white than cats that are Ss. Cats that are ss do not carry the Piebald mutation but may still have white caused by other mutations. Piebald can cause a greatly varying amount of white.
Why do breeders test for piebald spotting?
Testing for piebald spotting assists breeders with selection of matings that can produce the desired outcome for white. Note: expression of white patterns varies from breed to breed and among individuals within a breed. This test is specific for the mutation in MITF known to be associated with piebald/random white spotting.
Do dogs with S/S genotype have piebalds?
They may transmit this piebald variant to 50% of their offspring. Dogs with S/S genotype have two copies of this piebald variant and are expected to display some amount of white patterning. White patterning may be extensive in some breeds, with some individuals being nearly completely white.
