Question: Anerican shorthair cats are from what decent?

Context paragraphs:
Asian Semi-longhair: The Asian Semi-Longhair is a cat breed similar to the Asian Shorthair except it has semi-long fur.  The breed is also known by the name Tiffanie or Tiffany.  It is recognized in any of the Asian Shorthair or Burmese colors and patterns.  Like the Asian Shorthair, the breed was developed in Britain and is not currently recognized by any U.S. Registries.  It has full recognition in the GCCF.  It is related to, and in some registries distinct from, the Chantilly-Tiffany or Foreign Longhair, the North American variant.

Governing Council of the Cat Fancy: The Governing Council of the Cat Fancy (GCCF) is a cat registry, established in 1910 and the largest organisation that registers pedigree cats in the United Kingdom.  It was formed from a small number of cat clubs which were registering cats at the time when the modern cat fancy was in its first stages.  It is considered to be the original prototype for cat fancy registries.  It is an independent body with around 150 member clubs, including specialist breed clubs and area clubs covering particular regions.  The GCCF became an incorporated company on 5 November 2010.  It licenses cat shows put on by its affiliated clubs with about 135 shows per year.  Pedigree cats shown at these shows can gain the titles Champion, Grand Champion, Imperial Grand Champion and Olympian.  The latter having three levels, Bronze, Silver and Gold.  The word Champion is replaced by Premier for neutered cats.  The showing of non-pedigree cats (often referred to as Domestic shorthair and Domestic longhair) and Pedigree Pets is also popular at GCCF shows.

European Shorthair: The European Shorthair, also called the European or in WCF Celtic Shorthair, is a breed originating in Europe.  The term has also been used as an elaborate way of referring to common domestic cats of Europe, causing some confusion as the pedigree cats of this breed also should resemble the typical domestic cats of Europe.  This role was held until the beginning of the 20th century by the British Shorthair, even though stockier than the majority of common European cats, until 1949 when the European Shorthair was recognized by the Fédération internationale féline (FIFe).  The oldest known European Shorthair registered in FIFe was born in 1940, as the origin of the European Shorthair predates the formation of FIFe in 1949.  Breed standards describing the European Shorthair as an established breed can be found in different cat books from the 1930ies.

Domestic short-haired cat: A domestic short-haired cat is a cat of mixed ancestry – thus not belonging to any particular recognized cat breed – possessing a coat of short fur.  In British English, they are often referred to as moggies.  Domestic short-haired cats should not be confused with the British Shorthair, American Shorthair or other standardized breeds with "Shorthair" names, which are breeds recognized by various registries.  Domestic short-haireds are the most common cat in the United States, accounting for around 90–95% of their number.  Other generic terms include house cat and alley cat (the latter may be used more specifically to refer to feral specimens).  The term tabby cat technically refers to a coat pattern, but is also often used as a general term for cats of this sort.

American Shorthair: The American Shorthair (ASH) is a breed of domestic cat believed to be descended from European cats brought to North America by early settlers to protect valuable cargo from mice and rats.  According to the Cat Fancier's Association, in 2012, it was the seventh most popular breed of cat in the United States.

Bombay cat: The Bombay cat is a type of short-haired cat developed by breeding sable Burmese and black American Shorthair cats, to produce a cat of mostly Burmese type, but with a sleek, panther-like black coat.

American Ringtail: The American Ringtail Cat is a new experimental cat breed that started with a California cat named Solomon in 1998.  Owner Susan Manley started a breeding program to reproduce his unique curled tail, which she had also noted in other feral cats in northern California.  This genetic mutation seems to have no ill health effects associated with it.  The cats with curled tails were bred with Ragdoll cats and American Shorthair cats.  In 2005 The International Cat Association, gave this new breed “Registration Only” status.

Snowshoe cat: The Snowshoe is a rare breed of cat originating in the United States of America in the 1960s.  Snowshoes were first produced in Philadelphia when a Siamese breeder's cat gave birth to three kittens with white feet.  The breeder, Dorothy Hinds-Daugherty, then began a breeding program to produce what were originally called "Silver Laces", crossing the strangely marked Siamese cats with bi-color American Shorthair cats and other breeds.  When Hinds-Daugherty left the program, Vikki Olander began working with the cats and recruited new breeders, as well as worked towards full recognition within cat associations. Despite having existed for 45 years, Snowshoes are rare due to the difficulty of reproducing the correct coat markings.  The marks are based on recessive genes for color points and on the co-dominant but variably-expressed piebald pattern gene, making it difficult to predict the appearance of offspring.

CC (cat): CC, for "CopyCat" "or" "Carbon Copy" (born December 22, 2001), is a brown tabby and white domestic shorthair and the first cloned pet.  CC's surrogate mother was a tabby, but her genetic donor, Rainbow, was a calico domestic shorthair.  The difference in hair coloration between CC and Rainbow is due to epigenetic re-programming, which normally occurs in a fertilised embryo before implantation.

Colorpoint Shorthair: Colorpoint Shorthairs are a variety of domestic cat.  Depending on the cat registry, they may be considered a separate breed of cat, or more often a variant of a pre-existing one, if accepted at all.  These cats are distinguished by their conformance to wide range of sixteen different point colors, beyond the four standard Siamese colors.  The variety was initially created by crossbreeding Siamese with the American Shorthair – the same mixture that created the Oriental Shorthair, but with different goals.  The Colorpoint Shorthair shares the point-coloration pattern with the Siamese, but in the nontraditional colors of red, cream, tortoiseshell, and lynx (tabby) points, and minor variations thereof.  In body style, head shape, and other features, it may be intermediate between the two foundation breeds, which show cats leaning toward Siamese traits.  Those who favour the Traditional Siamese look may also favour the more moderate-typed Colourpoint Shorthairs that take after their American Shorthair ancestors in shape.
