The mutated gene is known to be the main cause of piebald patterns. One leading theory held that the patterns were caused by the mutated Kit gene slowing down the migration of pigment cells. The cells are produced at the back of the embryo and move through the skin towards the front as the animal develops in the womb.

What causes an animal to be piebald?
The piebald coloring is due to a genetic abnormality that leads to a lack of pigmentation in patches around the body. Piebaldism is a recessive trait; therefore, both parents must carry the recessive gene for there to be a chance that they will produce a piebald fawn.
What makes an animal pied?
A piebald or pied animal is one that has a pattern of unpigmented spots (white) on a pigmented background of hair, feathers or scales. ... Some animals also exhibit colouration of the irises of the eye that match the surrounding skin (blue eyes for pink skin, brown for dark).
Is piebald a genetic defect?
Piebaldism and Waardenburg syndromes are genetic disorders with similar features. Piebaldism appears as depigmented patches on the ventral side of the body, generally on the chin, forehead, chest, and abdomen (accompanied by a white forelock).
What gene is piebald?
A pattern of less symmetrical white spotting, often called piebald, parti, or random white, is present in many breeds. A DNA variant has been found in Microphthalmia Associated Transcription Factor- (MITF) gene that is associated with piebald spotting in many breeds.
What does piebald mean in horses?
Use the adjective piebald to describe something that has different colored patches — especially black and white patches. ... So something piebald has a combination of black and white coloring. It mostly refers to horses, although the word can be used to describe other multicolored things.
What causes a piebald squirrel?
The white on Chronister's neighborhood squirrel most likely is a piebald coloration as a result of leucism, sometimes, confusingly, called partial albinism. ... The Cornell Lab of Ornithology explains it this way: “Albinism is a genetic mutation that prevents the production of melanin in the body.
Is piebald 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.
What is the difference between piebald and skewbald horses?
Coloration. Piebald horses have large, irregular patches of black and white on their coats. Skewbald horses, on the other hand, have a combination of white and any other color -- typically brown, chestnut or bay. Both piebald and skewbald horses should have white markings that are continuous over the color base.
What is piebald mutation?
Human piebald trait is an autosomal dominant defect in melanocyte development characterized by patches of hypopigmented skin and hair. Although the molecular basis of piebaldism has been unclear, a phenotypically similar "dominant spotting" of mice is caused by mutations in the murine c-kit protooncogene.
Are piebald and vitiligo the same?
Piebaldism is unrelated to conditions such as vitiligo or poliosis. Although piebaldism may visually appear to be partial albinism, it is a fundamentally different condition. The vision problems associated with albinism are not usually present as eye pigmentation is normal.
Is piebald a disease?
Piebaldism is a genetic condition, typically present at birth, in which a person develops an unpigmented or white patch of skin or hair. The cells that determine eye, skin, and hair color are absent in certain areas in those with piebaldism. These cells are called melanocytes.
What is ocular albinism?
Ocular albinism is a genetic condition that primarily affects the eyes. This condition reduces the coloring (pigmentation) of the iris, which is the colored part of the eye, and the retina , which is the light-sensitive tissue at the back of the eye.
What is extreme piebald?
Piebald is defined as 'having patches of black and white or of other colors; parti-colored' (Dictionary.com). ... If the extreme piebald gene is present, pigment cells (melanocytes) are suppressed and these hairs may not develop properly.
What's the difference between piebald and dapple?
In terms of genetics, the difference between a piebald Dachshund and a dapple is that the piebald markings are caused by a recessive gene. Whereas the dapple markings are caused by a dominant gene. What is this? Both parents must carry the piebald gene to produce a piebald puppy.
What is ticking on a dog?
Put another way, ticking is a pattern of colored hair (usually extremely small spots of colored hair or coat flecks) that happens inside what would otherwise be white markings. Ticking is the color you'd see if the area hadn't been white.
