Sphynx Cat
The Sphynx cat (pronounced , ) also known as the Canadian Sphynx, is a breed of cat known for its lack of fur. Hairlessness in cats is a naturally occurring genetic mutation, and the Sphynx was developed through selective breeding of these animals, starting in the 1960s. The skin has a texture of chamois leather, as it has fine hairs, or the cat may be completely hairless. Whiskers may be present, either whole or broken, or may be totally absent. Per the breed standards, they have a somewhat wedge-shaped head with large eyes and ears, quite long legs and tail, and neat rounded paws. Their skin is the color that their fur would be, and all the usual cat markings (solid, point, van, tabby, tortie, etc.) may be found on the Sphynx cat's skin. Because they have no fur, Sphynx cats lose body heat more readily than coated cats, making them both warm to the touch and prone to seeking out warm places.

List Of Cat Breeds
Cat, Domestic cats have been diversified by humans into breeds and Felid hybrid, domestic and wild hybrids. Many such breeds recognized by various Cat registry, cat registries. Additionally, there are new and experimental breeds, landraces being established as standardized breeds, distinct domestic populations not being actively developed and lapsed (extinct) breeds. As of 2023, The International Cat Association (TICA) recognizes 75 standardized breeds, the Cat Fanciers' Association (CFA) recognizes 45, the Fédération Internationale Féline (FIFe) recognizes 50, the Governing Council of the Cat Fancy (GCCF) recognizes 45, and the World Cat Federation (WCF) recognizes 69. Inconsistency in a breed's classification and naming among registries means that an individual animal may be considered different breeds by different registries (though not necessarily eligible for registry in them all, depending on its exact ancestry). For example, TICA's Himalayan is considered a Point colorat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Pool
The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. Description A large gene pool indicates extensive genetic diversity, which is associated with robust populations that can survive bouts of intense selection. Meanwhile, low genetic diversity (see inbreeding and population bottlenecks) can cause reduced biological fitness and an increased chance of extinction, although as explained by genetic drift new genetic variants, that may cause an increase in the fitness of organisms, are more likely to fix in the population if it is rather small. When all individuals in a population are identical with regard to a particular phenotypic trait, the population is said to be 'monomorphic'. When the individuals show several variants of a particular trait they are said to be polymorphic. History The Russian geneticist Alexander Sergeevich Serebrovsky first formulated the concept in the 1920s as ''genofond'' (gene fund), ...

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. The GCCF 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, and Master Cat for cats competing in household pets. The showing of non-pedigree cats (often r ...

Russian Blue
The Russian Blue cat (), commonly referred to as just Russian Blue, is a pedigreed cat breed with solid blue colours that vary from a light shimmering silver to a darker, slate grey. The short, dense coat, which stands out from the body, has been the breed's hallmark for more than a century. Origin The Russian Blue is a Landrace, naturally occurring breed that may have originated in the port of Arkhangelsk in Russia.. They are also sometimes called Archangel Blues. It is believed that sailors took them from the Archangel Isles to Great Britain and Northern Europe in the 1860s. The first reference to an Archangel Cat appears in British print in 1862. The first recorded appearance of one in a show was in 1872 at The Crystal Palace in England as the Archangel Cat. However, Harrison Weir writing in 1895 reported that the early show cats under the Russian Blue name were British-bred grey tabbies, with separate grey cats arriving from Archangel in Britain in the 1800s with feature ...

Wild Type
The wild type (WT) is the phenotype of the typical form of a species as it occurs in nature. Originally, the wild type was conceptualized as a product of the standard "normal" allele at a locus, in contrast to that produced by a non-standard, " mutant" allele. "Mutant" alleles can vary to a great extent, and even become the wild type if a genetic shift occurs within the population. Continued advancements in genetic mapping technologies have created a better understanding of how mutations occur and interact with other genes to alter phenotype. It is now regarded that most or all gene loci exist in a variety of allelic forms, which vary in frequency throughout the geographic range of a species, and that a uniform wild type does not exist. In general, however, the most prevalent allele – i.e., the one with the highest gene frequency – is the one deemed wild type. The concept of wild type is useful in some experimental organisms such as fruit flies ''Drosophila melanogaster'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incompletely Dominant
In genetics, dominance is the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second is called recessive. This state of having two different variants of the same gene on each chromosome is originally caused by a mutation in one of the genes, either new (''de novo'') or inherited. The terms autosomal dominant or autosomal recessive are used to describe gene variants on non-sex chromosomes (autosomes) and their associated traits, while those on sex chromosomes (allosomes) are termed X-linked dominant, X-linked recessive or Y-linked; these have an inheritance and presentation pattern that depends on the sex of both the parent and the child (see Sex linkage). Since there is only one Y chromosome, Y-linked traits cannot be dominant or recessive. Additionally, there are other forms of dominance, such as incomplete do ...

Gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allele
An allele is a variant of the sequence of nucleotides at a particular location, or Locus (genetics), locus, on a DNA molecule. Alleles can differ at a single position through Single-nucleotide polymorphism, single nucleotide polymorphisms (SNP), but they can also have insertions and deletions of up to several thousand base pairs. Most alleles observed result in little or no change in the function or amount of the gene product(s) they code or regulate for. However, sometimes different alleles can result in different observable phenotypic traits, such as different pigmentation. A notable example of this is Gregor Mendel's discovery that the white and purple flower colors in pea plants were the result of a single gene with two alleles. Nearly all multicellular organisms have two sets of chromosomes at some point in their biological life cycle; that is, they are diploid. For a given locus, if the two chromosomes contain the same allele, they, and the organism, are homozygous with re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fédération Internationale Féline
The (FIFé) (International Feline Federation) is a federation of Cat registry, cat registries. There are currently forty-two member organizations in forty countries. Membership spans Europe, South America, and Asia. FIFé is one of the nine members of the World Cat Congress. History Founded by Marguerite Ravel, the federation was unofficially started in 1949 in Paris, France, at a meeting between the (French Cat Federation), the Royal Cat Society of Flanders, and the (Italian National Feline Association). At the organisation's first general assembly, in Ghent, Belgium, the federation was officially founded. For the occasion, all participants received a cat shaped statuette, in pink sandstone, that Marguerite Ravel had commissioned from the sculptor Jan and Joël Martel, Jan Martel. The original name was or FIFE. In 1972, the Brazilian Cat Club joined, making it necessary to change the Euro-centric name of the federation. The was dropped, and the abbreviation was changed to ...

Don Sphynx
The Donskoy cat, also known as Don Sphynx or Russian Hairless, is a hairless cat breed of Russian origin. It is not related to the better-known Sphynx cat (Canadian Hairless) whose characteristic hairlessness is caused by a recessive mutation in the keratin 71 gene. The Donskoy's hairlessness, on the other hand, is caused by a dominant mutation. History The Donskoy breed is able to be traced back to one kitten. This breed started in 1987 with the discovery of a hairless cat in the Russian city of Rostov-on-Don by cat breeder Elena Kovaleva. She had rescued a blue tortoiseshell kitten, which she named Varvara. At around four months of age, the cat began to lose fur. Varvara mated with a local tomcat and produced a litter of kittens. Some were born hairless, and the others started with hair but lost it like their mother. These kittens are the founding stock of the Donskoy breed and were later outcrossed with European Shorthair cats. Over time, breeders learned more about ...

Cornish Rex
The Cornish Rex is a cat breed, breed of domestic cat. The Cornish Rex only has down hair. Most breeds of cat have three different types of hair in their coats: the outer fur or "guard hairs", a middle layer called the "awn hair"; and the down hair or undercoat, which is very fine and about 1 cm long. Cornish Rexes only have the undercoat. The curl in their fur is caused by a different mutation and gene than that of the Devon Rex. The breed originated in Cornwall, Great Britain. Characteristics The coat of a Cornish Rex is extremely fine and naturally curly. Their light coat means that they are best suited for indoor living in warm and dry conditions, as they are sensitive to low temperatures. The breed is sometimes referred to as the Greyhound of the cats, because of the sleek appearance and the galloping run characteristic of the breed. Appearance According to the Governing Council of the Cat Fancy (GCCF) standard, the Cornish Rex's colour is irrelevant — therefore the ...
