Canadian Hairless, Sphynx Cat
|
Dermis and Epidermis (1975) from the Pearsons of Wadena, Minnesota, USA.
Bambi, Punkie, and Paloma (1978) found in Toronto, Canada and raised by Shirley Smith.
Other hairless breeds might have body shapes or temperaments that differ. There are, for example, new hairless breeds, including the Don Sphynx and the Peterbald from Russia, which arose from their own spontaneous mutations. The standard for the Sphynx differs between cat associations such as TICA, FIFE and CFA.
It has been theorized that Sphynx hairlessness might be produced by an allele of the same gene that produces the Devon Rex (re), with the Sphynx allele being incompletely dominant over the Devon allele and both recessive to the wild type. However a different genetic symbol (hr) is given to the Sphynx gene and it is more likely that these are different genes interacting with each other. The only allowable outcross breeds in the CFA are now the American Shorthair and Domestic Shorthair. Other associations may vary and the Russian Blue is a permitted outcross in the GCCF. In Europe mainly Devon Rex has been used for outcrosses.
