Here's a breakdown:
* Dominant Gene: The hairless trait in Sphynx cats is caused by a dominant gene. This means that even if only one parent carries the gene, their offspring have a chance of inheriting the hairless trait.
* Reduced Keratin Production: The gene mutation leads to a significant reduction in keratin production. This results in the cat's skin being thin and wrinkled, with very little hair.
* Variety of Hairlessness: While most Sphynx cats are practically hairless, some individuals have a very fine layer of fuzz called "peach fuzz".
* Not a Disease: The hairlessness is a genetic trait and not a disease. Sphynx cats are generally healthy and can live normal lives, though they need extra care due to their sensitive skin.
It's important to note:
* Not all hairless cats are Sphynx: Other breeds, like the Don Sphynx and the Peterbald, also exhibit hairlessness.
* Hairless cats are not hypoallergenic: While they don't produce as much dander as other cats, they can still trigger allergies in some people.
If you're interested in learning more about Sphynx cats, it's best to consult with a veterinarian or a breeder who specializes in this breed.
