The Disease |
|
Hairlessness is a genetic trait found in Chinese Crested, Peruvian Hairless Dog (Peruvian Inca Orchid) and Mexican Hairless Dog (Xoloitzcuintle). Hairlessness is caused by a dominant autosomal gene. Only one copy of the mutation is enough for the dog to be hairless. Dogs with two copies of the mutation die before birth. This means that all hairless dogs have one copy of the mutation. Hairless dogs have no hair on the body except on the crest, tail and feet. Hairless dogs are known to have teeth problems and are likely o lose teeth when they get older. Dogs which don't carry the muttion are covered with hair and known as Powder Puff. Powder Puff dogs don't experience the teeth problems which develop in carriers.

Trait of Inheritance |
Trait of inheritance:
in Chinese Cresteds, Mexican and Peruvians Hairless Dogs: Dominant and so one copy of the variant can cause hairlessness.
In Scottish Deerhound: Recessive and so the dog can only be hairless when it inherits two copies of the variant one from each parent. |
