Buckskin (horse)
Buckskin is a hair coat color of horses, referring to a color that resembles certain shades of tanned deerskin. Similar colors in some breeds of dogs are also called buckskin. The horse has a tan or gold colored coat with black points (mane, tail, and lower legs). Buckskin occurs as a result of the cream dilution gene acting on a bay horse. Therefore, a buckskin has the Extension, or "black base coat" (E) gene, the agouti gene (A) gene (see bay for more on the agouti gene), which restricts the black base coat to the points, and one copy of the cream gene (CCr), which lightens the red/brown color of the bay coat to a tan/gold. Buckskins should not be confused with dun-colored horses, which have the dun dilution gene, not the cream gene. Duns always have primitive markings (shoulder blade stripes, dorsal stripe, zebra stripes on legs, webbing). However, it is possible for a horse to carry both dilution genes; these are called "buckskin duns" or sometimes "dunskins." Also, ...

Dun (color)
The dun gene is a dilution gene that affects both red and black pigments in the coat color of a horse. The dun gene lightens most of the body while leaving the mane, tail, legs, and primitive markings the shade of the undiluted base coat color. A dun horse always has a dark dorsal stripe down the middle of its back, usually has a darker face and legs, and may have transverse striping across the shoulders or horizontal striping on the back of the forelegs. Body color depends on the underlying coat color genetics. A classic "bay dun" is a gray-gold or tan, characterized by a body color ranging from sandy yellow to reddish brown. Duns with a chestnut base may appear a light tan shade, and those with black base coloration are a smoky gray. Manes, tails, primitive markings, and other dark areas are usually the shade of the undiluted base coat color. The dun gene may interact with all other coat color alleles.

Equine Coat Color Genetics
Equine coat color genetics determine a horse's coat color. Many colors are possible, but all variations are produced by changes in only a few genes. The "base" colors of the horse are determined by the Extension locus, which in recessive form (e) creates a solid chestnut (coat), chestnut or "red" coat. When dominant (E), a horse is black (horse), black. The next gene that strongly affects coat color, Agouti, when present on a horse dominant for E, limits the black color to the points, creating a shade known as Bay (horse), Bay that is so common and dominant in horses that it is informally grouped as a "base" coat color. Over these three "base" colors can be any number of dilution genes and patterning genes. The dilution genes include the wildtype dun gene, believed to be one of the oldest colors extant in horses and donkeys. Depending on whether it acts on a bay, black, or chestnut base coat, it produces the colors known as bay dun, grullo, and red dun. Another common dilution ...

Equine Coat Color
Horses exhibit a diverse array of coat colors and distinctive markings. A specialized vocabulary has evolved to describe them. While most horses remain the same color throughout life, a few, over the course of several years, will develop a different coat color from that with which they were born. Most white markings are present at birth, and the underlying skin color of a healthy horse does not change. Some Equine coat colors are also related to the breed of horse, like the Friesian breed for instance. The basic outline of equine coat color genetics has largely been resolved, and DNA tests to determine the likelihood that a horse will have offspring of a given color have been developed for some colors. Discussion, research, and even controversy continues about some of the details, particularly those surrounding spotting patterns, color sub-shades such as "sooty" or " flaxen", and markings. Basic coat colors The two basic pigment colors of horse hairs are pheomelanin ("red") ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cream Gene
The cream gene is responsible for a number of horse coat colors. Horses that have the cream gene in addition to a base coat color that is chestnut will become palomino if they are heterozygous, having one copy of the cream gene, or cremello, if they are homozygous. Similarly, horses with a bay base coat and the cream gene will be buckskin or perlino. A black base coat with the cream gene becomes the not-always-recognized smoky black or a smoky cream. Cream horses, even those with blue eyes, are not white horses. Dilution coloring is also not related to any of the white spotting patterns. The cream gene (''CCr'') is an incomplete dominant allele with a distinct dosage effect. The DNA sequence responsible for the cream colors is the cream allele, which is at a specific locus on the solute carrier family 45 member 2 (''SLC45A2'') gene (previously known as ''MATP'' and ''OCA4'', among others). Its general effect is to lighten the coat, skin and eye colors. When one copy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
True-breeding Organism
A true-breeding organism, sometimes also called a purebred ''(biology slang: pure line'' or ''true-breeding line)'', is an organism that always passes down certain phenotypic traits (i.e. physically expressed traits) to its offspring of many generations. An organism is referred to as true breeding for each trait to which this applies, and the term "true-breeding" is also used to describe individual genetic traits. In Mendelian genetics, this means that an organism must be homozygous for every trait for which it is considered true breeding; that is, the pairs of alleles that express a given trait are the same. In a purebred strain or breed, the goal is that the organism will "breed true" for the breed-relevant traits. Apomixis and parthenogenesis, types of asexual reproduction, also result in true breeding, although the organisms are usually not homozygous. Examples A purebred variety of cat, such as Siamese, only produces kittens with Siamese characteristics because their ancest ...

Allele
An allele (, ; ; modern formation from Greek ἄλλος ''állos'', "other") is a variation of the same sequence of nucleotides at the same place on a long DNA molecule, as described in leading textbooks on genetics and evolution. ::"The chromosomal or genomic location of a gene or any other genetic element is called a locus (plural: loci) and alternative DNA sequences at a locus are called alleles." The simplest alleles are single nucleotide polymorphisms (SNP). but they can also be insertions and deletions of up to several thousand base pairs. Popular definitions of 'allele' typically refer only to different alleles within genes. For example, the ABO blood grouping is controlled by the ABO gene, which has six common alleles (variants). In population genetics, nearly every living human's phenotype for the ABO gene is some combination of just these six alleles. Most alleles observed result in little or no change in the function of the gene product it codes for. However, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Breed
A color breed refers to groupings of horses whose registration is based primarily on their coat color, regardless of the horse's actual breed or breed type. Some color breeds only register horses with a desired coat color if they also meet specific pedigree criteria, others register animals based solely on color, regardless of parentage. A few pedigree-based color breeds, notably the American Paint Horse and the Appaloosa, confronted with the reality of many animals born without the proper color even though they are from two registered parents, have modified their rules to allow registration of animals with the proper pedigree even if they do not possess the proper color. On the other hand, with the prevalence of DNA testing for parentage, many horses once forced into color breed status due to being born the "wrong" color and thus deemed undesirable or of questionable parentage by many regular breed registries with cropout rules can now be accepted for registration.

List Of Horse Breeds
This article is a list of horse and pony breeds with articles on Wikipedia, and also includes terms for types of horse that are not necessarily standardized breeds but are often labeled as breeds. While there is no scientifically accepted definition of the term "breed",The state of the world's animal genetic resources for food and agriculture. Barbara Rischkowsky and Dafydd Pilling. Commission on Genetic Resources for Food and Agriculture. 2007 a breed is generally defined as having distinct true-breeding characteristics over a number of generations. Its members may be called "purebred". In most cases, bloodlines of horse breeds are recorded with a breed registry. The concept is somewhat flexible in horses, as open stud books are created for recording pedigrees of horse breeds that are not yet fully true-breeding. Registries also are considered the authority as to whether a given breed is listed as a "horse" or a "pony". There are also a number of "color breed", sport horse, ...
