This is a result of
the hairless gene that sometimes causes the dog to have fewer teeth than other breeds.
Many American hairless terriers are, as advertised, bare - skinned, though others have short coats but carry
the hairless gene.
On the other hand, a Powderpuff bred to another Powderpuff can never produce hairless puppies, since they do not carry
the Hairless gene.
Expressing
the Hairless gene in some cells rescued mutant mice from the chill of baldness.
Hadassah University Medical Center claims the world's largest collection of patients with genetic hair diseases, including roughly half the documented cases of papular atrichia, the condition Christiano linked to
the hairless gene.
Still, by identifying the human
hairless gene as an important master switch in regulating cell death in a hair follicle — a discovery that could lead to gene therapies for unwanted hair growth — Christiano emerged as a new star in the field, and a glamorous one.
[3] Zygotes affected with double
hairless genes (1 in 4) never develop into puppies, and are reabsorbed in the womb.
Not exact matches
Research led by Margery Smelkinson found that NS1 modulates the activitiy of a signaling cascade known as the Hedgehog pathway (so named because fruit fly larvae lacking the Hedgehog
gene emerge
hairless and resemble tiny hedgehogs).
The researchers confirmed this by engineering the
Hairless mutant mice to express a working copy of the
gene just in their PK cells.
It may interest you to know that the
gene that produces
hairless Cresteds is also linked to teeth problems.
Breeding / Reproduction The Chinese Crested
Hairless and the Chinese Crested Powderpuff both carry a copy of the Powderpuff
gene, and for this reason both types are often found in the same litter.
But smaller breeds have their problems as well, like the Bashkir Curly where many breeders continue to use and promote the use of
hairless (extreme / baldy *) horses in breeding based on the anecdote that they are homozygous for the curly coat
gene; these are horses who are defenseless to weather extremes (head & cold) and bugs (no manes, no tail hair, many times large swaths of their body
hairless as well).

The
hairless trait that makes these dogs so unusual is actually an incomplete dominant
gene and many of the Chinese Cresteds have full coats (Powderpuff varieties).
