Tricolor Cat
A calico cat is a domestic cat of any breed with a tri-color coat. The calico cat is most commonly thought of as being 25% to 75% white with large orange and black patches; however, they may have other colors in their patterns. Calico cats are almost exclusively female except under rare genetic conditions. A calico cat is not to be confused with a tortoiseshell, that has a black undercoat and a mostly mottled coat of black/red or blue/cream with relatively few to no white markings. However, outside of North America, the calico pattern is more commonly called ''tortoiseshell and white''. Such cats with diluted coloration (blue tortoiseshell and white) have been called ''calimanco'' or ''clouded tiger''. Occasionally, the tri-color calico coloration is combined with a tabby patterning, called ''tortoiseshell tabby with white.'' A calico-patched tabby cat may be referred to as ''caliby''. Derived from a colorful printed calico fabric, when the term "calico" is applied to cats, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Domestic Cat
The cat (''Felis catus''), also referred to as the domestic cat or house cat, is a small Domestication, domesticated carnivorous mammal. It is the only domesticated species of the family Felidae. Advances in archaeology and genetics have shown that the domestication of the cat occurred in the Near East around 7500 BC. It is commonly kept as a pet and working cat, but also ranges freely as a feral cat avoiding human contact. It is valued by humans for companionship and its ability to kill vermin. Its retractable claws are adapted to killing small prey species such as mice and rats. It has a strong, flexible body, quick reflexes, and sharp teeth, and its night vision and sense of smell are well developed. It is a social species, but a solitary hunter and a crepuscular predator. Cat intelligence is evident in their ability to adapt, learn through observation, and solve problems. Research has shown they possess strong memories, exhibit neuroplasticity, and display cognitive skil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X Chromosome
The X chromosome is one of the two sex chromosomes in many organisms, including mammals, and is found in both males and females. It is a part of the XY sex-determination system and XO sex-determination system. The X chromosome was named for its unique properties by early researchers, which resulted in the naming of its counterpart Y chromosome, for the next letter in the alphabet, following its subsequent discovery. Discovery It was first noted that the X chromosome was special in 1890 by Hermann Henking in Leipzig. Henking was studying the testicles of '' Pyrrhocoris'' and noticed that one chromosome did not take part in meiosis. Chromosomes are so named because of their ability to take up staining (''chroma'' in Greek means ''color''). Although the X chromosome could be stained just as well as the others, Henking was unsure whether it was a different class of the object and consequently named it ''X element'', which later became X chromosome after it was established that it w ...

X-inactivation
X-inactivation (also called Lyonization, after English geneticist Mary Lyon) is a process by which one of the copies of the X chromosome is inactivated in therian female mammals. The inactive X chromosome is silenced by being packaged into a transcriptionally inactive structure called heterochromatin. As nearly all female mammals have two X chromosomes, X-inactivation prevents them from having twice as many X chromosome gene products as males, who only possess a single copy of the X chromosome (see dosage compensation). The choice of which X chromosome will be inactivated in a particular embryonic cell is random in placental mammals such as humans, but once an X chromosome is inactivated it will remain inactive throughout the lifetime of the cell and its descendants in the organism (its cell line). The result is that the choice of inactivated X chromosome in all the cells of the organism is a random distribution, often with about half the cells having the paternal X chrom ...

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 ...

Calico
Calico (; in British usage since 1505) is a heavy plain-woven textile made from unbleached, and often not fully processed, cotton. It may also contain unseparated husk parts. The fabric is far coarser than muslin, but less coarse and thick than canvas or denim. However, it is still very cheap owing to its unfinished and undyed appearance. The fabric was originally from the city of Calicut in southwestern India. It was made by the traditional weavers called cāliyans. The raw fabric was dyed and printed in bright hues, and calico prints became popular in Europe. History Origins Calico originated in Calicut, from which the name of the textile came, in South India, now Kerala, during the 11th century, where the cloth was known as "chaliyan". It was mentioned in Indian literature by the 12th century when the polymath and writer Hemachandra described calico fabric prints with a lotus design.''Encyclopædia Britannica'' (2008)"calico" Calico was woven using Gujarati cotton from Su ...

Baltimore Checkerspot Butterfly
The Baltimore checkerspot (''Euphydryas phaeton'') is a North American butterfly of the family Nymphalidae. It has been the official state insect of the U.S. State of Maryland since 1973. The Baltimore checkerspot was named for the first Lord Baltimore due to its similarity of colors in the family crest. Despite the species status as Maryland state insect, the population in Maryland has faced significant decline and is currently listed by the Maryland Department of Natural Resources as "rare, threatened, and endangered" animal list. Life cycle During its period of growth, the checkerspot butterfly will search for a host plant for nourishment. Its native larval host is the white turtle head (''Chelone glabra''), but it has also to some extent made use of the introduced lawn weed English plantain (''Plantago lanceolata'') and other plants. Unlike most butterflies and moths, which overwinter as eggs, pupae, or sometimes adults, the Baltimore checkerspot overwinters as larvae. In ...

Baltimore Oriole
The Baltimore oriole (''Icterus galbula'') is a small icterid, icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the Flag of Maryland, coat-of-arms of 17th-century Cecilius Calvert, 2nd Baron Baltimore, Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole ''Icterus bullockii'', led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly. The Baltimore oriole is the List of U.S. state birds, state bird of Maryland, and the namesake and mascot for the Baltimore Orioles baseball team. Taxonomy The Baltimore oriole was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Syste ...

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication ( translesion synthesis). Mutations may also result from substitution, insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics ( phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutati ...
