Cat Coat Genetics
Cat coat genetics determine the coloration, pattern, length, and texture of feline fur. Understanding how can be challenging because many genes are involved. The variations among cat coats are physical properties and should not be confused with cat breeds. A cat may display the coat of a certain breed without actually being that breed. For example, a Siberian cat, Siberian could wear point coloration, the stereotypical coat of a Siamese cat, Siamese. Solid colors Eumelanin The browning gene ''B/b/bl'' codes for TYRP1 (), an enzyme involved in the metabolic pathway for eumelanin pigment production. Its dominant form, ''B'', will produce black eumelanin. It has two recessive variants, ''b'' (chocolate) and ''bl'' (cinnamon), with ''bl'' being recessive to both ''B'' and ''b''. Chocolate is a rich dark brown color, and is referred to as chestnut in some breeds. Cinnamon is a light reddish brown, but is sometimes not reddish at all. Sex-linked orange/red The sex-linked ' ...

Melanophilin
Melanophilin is a carrier protein which in humans is encoded by the ''MLPH'' gene. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. Function This gene encodes a member of the exophilin subfamily of Rab effector proteins. The protein forms a ternary complex with the small Ras-related GTPase Rab27A in its GTP-bound form and the motor protein myosin Va. A similar protein complex in mouse functions to tether pigment-producing organelles called melanosomes to the actin cytoskeleton in melanocytes, and is required for visible pigmentation in the hair and skin. In melanocytic cells MLPH gene expression may be regulated by MITF. Clinical significance A mutation in this gene results in Griscelli syndrome type 3, which is characterized by a silver-gray hair color and abnormal pigment distribution in the hair shaft. Mutations in melanophilin cause the "dilute" coat color ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Epistatic
Epistasis is a phenomenon in genetics in which the effect of a gene mutation is dependent on the presence or absence of mutations in one or more other genes, respectively termed modifier genes. In other words, the effect of the mutation is dependent on the genetic background in which it appears. Epistatic mutations therefore have different effects on their own than when they occur together. Originally, the term ''epistasis'' specifically meant that the effect of a gene variant is masked by that of a different gene. The concept of ''epistasis'' originated in genetics in 1907 but is now used in biochemistry, computational biology and evolutionary biology. The phenomenon arises due to interactions, either between genes (such as mutations also being needed in regulators of gene expression) or within them (multiple mutations being needed before the gene loses function), leading to non-linear effects. Epistasis has a great influence on the shape of evolutionary landscapes, which le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agouti Signaling Protein
Agouti-signaling protein is a protein that in humans is encoded by the ASIP gene. It is responsible for the distribution of melanin pigment in mammals. Agouti interacts with the melanocortin 1 receptor to determine whether the melanocyte (pigment cell) produces phaeomelanin (a red to yellow pigment), or eumelanin (a brown to black pigment). This interaction is responsible for making distinct light and dark bands in the hairs of animals such as the agouti, which the gene is named after. In other species such as horses, agouti signalling is responsible for determining which parts of the body will be red or black. Mice with wildtype agouti will be grey, with each hair being partly yellow and partly black. Loss of function mutations in mice and other species cause black fur coloration, while mutations causing expression throughout the whole body in mice cause yellow fur and obesity. The agouti-signaling protein (ASIP) is a competitive antagonist with alpha-Melanocyte-stimulating hormon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agouti (coloration)
Agouti is a type of fur coloration in which each hair displays two or more bands of pigmentation. The overall appearance of agouti fur is usually gray or dull brown, although dull yellow is also possible. Agouti fur is characterized by an appearance of being composed of hairs of different colors, separate from definite markings (although agouti can appear in combination with other markings, such as spots, stripes or patches). This effect is caused by different ''portions'' of each hair being visible, such that different colors of the hair's banding is seen, despite hairs actually having similar coloration. This effect produces a very distinctive, finely "speckled" appearance similar to "salt and pepper" hair, as well as an iridescent effect very similar to shot silk which causes the overall color to appear to shift subtly depending on the angle of the light or when the animal moves. Agouti fur is the wild type pigmentation for many domesticated mammals. It is a highly recognized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eyeliner
Eye liner or eyeliner is a cosmetic used to define the eyes. It is applied around the contours of the eye(s). It is often used to create various aesthetic effects. History Eye liner was first used in ancient India, ancient Egypt and Mesopotamia as a dark black line around the eyes. As early as 10,000 BC, Egyptians and Mesopotamians wore various cosmetics including eye liner not only for aesthetics but to protect the skin from the desert sun. Research has also speculated that eye liner was worn to protect the wearer from the evil eye. The characteristic of having heavily lined eyes has been frequently depicted in ancient Egyptian art. They produced eye liner with a variety of materials, including copper ore and antimony. Ancient Egyptian kohl contained galena, which was imported from nearby regions in the Land of Punt, Coptos and Western Asia.''Studies in Ancient Technology'', Volume III, (Brill Archive), p.18. In the 1960s, liquid eye liner was used to create thick black and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tabby Cat
A tabby is any domestic cat (''Felis catus'') with a distinctive 'M'-shaped marking on its forehead; stripes by its eyes and across its cheeks, along its back, and around its legs and tail; and (differing by tabby type), characteristic striped, dotted, lined, flecked, banded, or swirled patterns on the body—neck, shoulders, sides, flanks, chest, and abdomen. "Tabby" is not a breed of cat, but a coat type seen in almost all genetic lines of domestic cats, regardless of status. The tabby pattern is found in many official cat breeds and is a hallmark of the landrace extremely common among the general population of 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 their 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 colorati ...

CAT2007 05 16
The cat (''Felis catus'') is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to kill rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to the other felid species: they have a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Their night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language. Although the cat is a social species, they are a solitary hunter. As a pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
