Acromelanism
Acromelanism is a genetic condition that results in pigmentation being affected by temperature. It results in point coloration where the extremities of an animal are a different colour to the rest of the body. It is commonly known for the coloration of Siamese and related breeds of cat, but can be found in many other species including dogs, rabbits, rats, mice, guinea pigs, minks, and gerbils. It is a specific type of point coloration. Description Colorpoint patterns are where the extremities (paws, face, ears and tail) of the animal are colored differently compared to the rest of the body. The areas with different color may be referred as 'points' or being 'pointed'. Color can spread to the rest of the body, but is concentrated on the extremities. Colorpoint patterns occur due to acromelanism, which is a type of partial albinism where pigmentation is affected by temperature. Cold temperatures trigger pigment development while warm temperatures decrease pigment development. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point Coloration
Points are specific areas of an animal coat that are colored differently from the main body colorations. Point coloration may be represented by a pale body color and relatively darker extremities, such as face, ears, feet, tail, and external sex organs, as seen on Siamese cats. However, colored points can be found in many mammal species and some points are lighter than the main body color. Temperature-dependent colorpoint In many species, colorpoint patterns come from a genetic mechanism causing pigment to be produced only in cooler areas of the body, called acromelanism. This can be seen in cats, dogs (rare), fancy rats, guinea pigs, and rabbits.

Neighbours Siamese
''Neighbours'' is an Australian television soap opera that has aired since 18 March 1985. It was created by television executive Reg Watson. The Seven Network commissioned the show following the success of Watson's earlier soap ''Sons and Daughters (Australian TV series), Sons and Daughters''. Although successful in Melbourne, ''Neighbours'' underperformed in the Sydney market and was cancelled by Seven four months after it began airing. It was immediately commissioned by rival Network 10, Network Ten for a second production season, which began screening on 20 January 1986. ''Neighbours'' became the longest-running drama series in Australian television history. In 2005, it was inducted into the Logie Hall of Fame. The storylines concern the lives of the people who live and work in Erinsborough, a fictional suburb of Melbourne, Victoria, Australia, Victoria. The series centres on the residents of Ramsay Street, a dead end street, and its neighbouring area, the Lassiters c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrexia
Fever or pyrexia in humans is a symptom of an anti-infection defense mechanism that appears with body temperature exceeding the normal range caused by an increase in the body's temperature set point in the hypothalamus. There is no single agreed-upon upper limit for normal temperature: sources use values ranging between in humans. The increase in set point triggers increased muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes flushed, and may begin to sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral, bacterial, and parasitic infections—such as influenza, the common cold, meningitis, urinary tract infections, append ...

List Of Rabbit Breeds
As of 2017, there were at least 305 breeds of the domestic rabbit in 70 countries around the world raised for in the Agriculture, agricultural practice of Selective breeding, breeding and raising domestic rabbits as livestock for their value in meat, fur, wool, education, Scientific method, scientific research, entertainment and companionship in cuniculture. A rabbit breed is a distinct strain created through selective breeding (or occasionally natural selection) for specific characteristics, including size, fur, body type, color, feed conversion ratio, et cetera. Organizations such as the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC) have standards for the desired qualities of their respective recognized breeds. Each rabbit breed is considered to benefit when a reputable breeder strives to emulate the perfect example for the breed, defined by the individual breed standard by which it may be judged.

Neva Masquerade
The Neva Masquerade is a breed or sub-breed of semi-longhaired domestic cat, which originates in Russia. It is the sister breed or Point coloration, colourpoint variant of the Siberian cat, a Pedigreed cat, pedigreed breed Selective breeding, selecively bred from a centuries-old Russian landrace. The colourpoint markings are the result of a colourpoint gene, originally found in Asian cats. The Neva Masquerade is believed to be derived from crossing the Siberian cat with Asian colourpointed landrace cats, or possibly pedigree cats related to those, such as the Himalayan cat, Himalayan (colourpointed Persian cat, Persian), Siamese cat, Siamese or Thai cat, Thai breed. Some cat registries classify the Neva Masquerade as a colourpoint variety or sub-breed of the Siberian cat, while others consider it to be a separate sister breed. Regardless of its classification, all Neva Masquerade cats are Selective breeding, selectively bred and Pedigree (cat), pedigreed today in all major Cat ...

Siberian Cat
The Siberian is a centuries-old landrace (natural variety) of domestic cat in Russia, and recently developed as a formal breed with standards promulgated the world over since the late-1980s. Since 2006, the breed is recognised for registry and championship status with all major cat registries. The formal name of the breed is Siberian Forest Cat, but it is typically referred to as the Siberian or Siberian cat. Formerly, sometimes the names Moscow Semi-Longhair and Russian Longhair were also used. The colourpoint variant or sister breed, called the Neva Masquerade, is categorised as a separate cat breed by some registries, including FIFe, WCF, and ACF. The breed developed from an ancient, natural landrace from Siberia, and is the national cat of Russia. While it began as a landrace, Siberians are selectively bred and pedigreed in all major cat fancier and breeder organisations. This means that all Siberian cats are purebred cats with a formally registered ancestry. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foundation Stock
Foundation stock or foundation bloodstock refers to animals that are the progenitors, or foundation, of a breed or of a given bloodline within such. Many modern breeds can be traced to specific, named foundation animals, but a group of animals may be referred to collectively as foundation bloodstock when one distinct population (including both landrace breeds or a group of animals linked to a deliberate and specific selective breeding program) provides part of the underlying genetic base for a new distinct population. Terminology The terms for foundation ancestors differ by sex, most commonly "foundation sire" for the father and "foundation dam" for the mother. Depending upon the species in question, more specialized terms may be used, such as ''foundation mare'' for female horses, ''foundation queen'' for female cats, or ''foundation bitch'' for female dogs. The offspring of genetically dissimilar parents or stock, whether of different species or different breeds are technically ...

Tabby Cat
A tabby cat, or simply tabby, is any domestic cat (''Felis catus'') with a Cat_coat_genetics#Tabbies , coat pattern distinguished by an M-shaped marking on its forehead, stripes by its eyes and across its cheeks, along its back, around its legs and tail, and characteristic striped, dotted, lined, flecked, banded, or swirled patterns on the body: neck, shoulders, sides, flanks, chest. The four known distinct patterns, each linked to genetics, are the mackerel, classic or blotched, ticked, and spotted tabby patterns. "Tabby" is not a Cat breeds, breed of cat but a coat pattern. It is common among Moggy, non-pedigree cats around the world. The tabby pattern occurs naturally and is connected both to the coat of the domestic cat's direct ancestor and to those of its close relatives: the African wildcat (''Felis lybica lybica''), the European wildcat (''Felis silvestris''), and the Asiatic wildcat (''Felis lybica ornata''), all of which have similar coats, both by pattern and colorat ...

Tortoiseshell Cat
Tortoiseshell is a cat animal coloration, coat coloring named for its similarity to tortoiseshell pattern. Like tortoiseshell-and-white or Calico cat, calico cats, tortoiseshell cats are almost exclusively female. Male tortoiseshells are rare and are usually sterile.Atkins (2003), p.105 Tortoiseshell cats, or torties, combine two colors other than white, either closely mixed or in larger patches. The colors are often described as red and black, but the "red" patches can instead be orange, yellow, or cream, and the "black" can instead be chocolate, gray, tabby cat, tabby, or blue. Tortoiseshell cats with the tabby cat, tabby pattern as one of their colors are sometimes referred to as torbies or torbie cats. "Tortoiseshell" is typically reserved for multicolored cats with relatively small or no white markings. Those that are predominantly white with tortoiseshell patches are described as tricolor, tortoiseshell-and-white, or calico cat, calico. Tortoiseshell markings appear in m ...

Bengal Cat
The Bengal cat is a breed of hybrid cat created from crossing of an Asian leopard cat (''Prionailurus bengalensis'') with domestic cats, especially the spotted Egyptian Mau. It is then usually bred with a breed that demonstrates a friendlier personality, because after breeding a domesticated cat with a wildcat, its friendly personality may not manifest in the kitten. The breed's name derives from the leopard cat's taxonomic name. Bengals have varying appearances. Their coats range from spots, rosettes, arrowhead markings, to marbling. History Early history The earliest mention of an Asian leopard cat × domestic cross was in 1889, when Harrison Weir wrote of them in ''Our Cats and All About Them''. Bengals as a breed Jean Mill of California is given credit for the modern Bengal breed. She made the first known deliberate cross of an Asian leopard cat with a domestic cat (a black California tomcat). Bengals as a breed did not really begin in earnest until much ...
