Sooty Gene
A sooty or smutty Equine coat color, horse coat color is characterized by black or darker hairs mixed into a horse's coat, typically concentrated along the topline of the horse and less prevalent on the underparts. The effect is especially pronounced on buckskin (horse), buckskins and palominos. Sootiness is believed to be an inherited trait involving multiple genes, however the details are not yet known. Horses without any visible sooty coloration are termed "clear-coated." On bay horse, bay-based horses, the most common type of sooty is black countershading. This darkens the top side of the horse, sometimes turning the back, croup, and shoulder almost black, while leaving the underside of the horse redder. At its darkest, this effect may be confused with Seal brown (horse), seal brown, while in minimal forms the dark hairs may not be noticed. Dapples of red often appear within the dark region. Many horses with the sooty trait have a darker mask on the bony parts of the face. O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linseed
Flax, also known as common flax or linseed, is a flowering plant, ''Linum usitatissimum'', in the family Linaceae. It is cultivated as a food and fiber crop in regions of the world with temperate climates. In 2022, France produced 75% of the world's supply of flax. Textiles made from flax are known in English as linen and are traditionally used for bed sheets, underclothes, and table linen. Its oil is known as linseed oil. In addition to referring to the plant, the word "flax" may refer to the unspun fibers of the flax plant. The plant species is known only as a cultivated plant and appears to have been domesticated just once from the wild species '' Linum bienne'', called pale flax. The plants called "flax" in New Zealand are, by contrast, members of the genus ''Phormium''. Description Several other species in the genus ''Linum'' are similar in appearance to ''L. usitatissimum'', cultivated flax, including some that have similar blue flowers, and others with white, y ...

Primitive Markings
Primitive markings are a group of equine coat color, hair coat markings and qualities seen in several equine species, including horses, donkey, donkeys, and asses. In horses, they are associated with primitive breeds, though not limited to such breeds. The markings are particularly associated with the Dun gene, dun coat color family. All dun horses possess at least the Dorsal (anatomy), dorsal stripe, but the presence of the other primitive markings varies. Other common markings may include horizontal striping on the legs, transverse striping across the shoulders, and lighter guard hairs along the edges of a dark mane and tail. Origin The dun coat and attendant primitive or "dun factor" markings reflect the wild type coat and are observed in all Equus (genus), equine species. Some cave paintings depict horses as being dun and with the primitive markings. The Przewalski's horse is dun-colored with primitive markings. So, too, are horse breeds such as the Konik and the Heck hors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Recessive
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 incompl ...

Freiberger
The Freiberger or Franches-Montagnes is a Swiss breed of horse of light draught type. It originates in the Canton of Jura in north-western Switzerland, and is named for the Freiberge or Franches-Montagnes District in the south of that canton. It is widely distributed in Switzerland, and is also present in France and Belgium. It was formerly used principally as a farm horse or by the Swiss army; it is now used mainly for driving and riding. The is an annual fair for the breed held in Saignelégier, capital of the Franches-Montagnes District. History The Freiberger originates in the historic Jura region of Switzerland; use of horses in agricultural work and as post-horses is documented there from about 1620. By the early nineteenth century, there were active breeders in the district of Franches-Montagnes. In 1817, there were breeding mares. The horses were bred for use in agriculture and by the army as pack animals and artillery horses. There were imports of Angl ...

Dorsum (biology)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, '' Terminolog ...

Polygenic
A polygene is a member of a group of non- epistatic genes that interact additively to influence a phenotypic trait, thus contributing to multiple-gene inheritance (polygenic inheritance, multigenic inheritance, quantitative inheritance), a type of non-Mendelian inheritance, as opposed to single-gene inheritance, which is the core notion of Mendelian inheritance. The term "monozygous" is usually used to refer to a hypothetical gene as it is often difficult to distinguish the effect of an individual gene from the effects of other genes and the environment on a particular phenotype. Advances in statistical methodology and high throughput sequencing are, however, allowing researchers to locate candidate genes for the trait. In the case that such a gene is identified, it is referred to as a quantitative trait locus (QTL). These genes are generally pleiotropic as well. The genes that contribute to type 2 diabetes are thought to be mostly polygenes. In July 2016, scientists reported ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheat Middlings
Wheat middlings (also known as millfeed, wheat mill run, or wheat midds) are the product of the wheat milling process that is not flour. A good source of protein, fiber, phosphorus, and other nutrients, they are a useful fodder for livestock and pets. They are also being researched for use as a biofuel. Production White flour is made entirely from the endosperm or protein/starchy part of the grain, leaving behind the germ and the bran or fiber part. In addition to marketing the bran and germ as products in their own right, middlings include ''shorts'' (making up approximately 12% of the original grain, consisting of fractions of endosperm, bran, and germ with an average particle size of 500–900 microns) and ''red dog'' (actually a low-grade flour, making up approximately 3% of the original grain, consisting of fractions of endosperm and bran, with an average particle size of 100–300 microns). The middlings include those portions of the wheat kernel that are richest in proteins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copra
Copra (from ; ; ; ) is the dried, white flesh of the coconut from which coconut oil is extracted. Traditionally, the coconuts are sun-dried, especially for export, before the oil, also known as copra oil, is pressed out. The oil extracted from copra is rich in lauric acid, making it an important commodity in the preparation of lauryl alcohol, soaps, fatty acids, cosmetics, etc. and thus a lucrative product for many coconut-producing countries. The palatable oil cake, known as copra cake, obtained as a residue in the production of copra oil is used in animal feeds. The ground cake is known as coconut or copra meal. Production Copra has traditionally been grated and ground, then boiled in water to extract coconut oil. It was used by Pacific island cultures and became a valuable commercial product for merchants in the South Seas and South Asia in the 1860s. Nowadays, coconut oil (70%) is extracted by crushing copra; the by-product is known as copra cake or copra meal (30 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Horse
Black is a hair coat color of horses in which the entire hair coat is black. It is not uncommon to mistake dark chestnuts or bays for black. Black horses have dark brown eyes, black skin, and wholly black hair coats without any areas of permanently reddish or brownish hair. They may have pink skin beneath any white markings under the areas of white hair, and if such white markings include one or both eyes, the eyes may be blue. Many black horses "sun bleach" with exposure to the elements and sweat, and therefore their coats may lose some of their rich black character and may even resemble bay or seal brown, though examination of the color of hair around the eyes, muzzle and genitals will determine color. Some breeds of horses, such as the Friesian horse, Murgese and Ariegeois (or Merens), are almost exclusively black. Black is also common in the Fell pony, Dales pony, Ostfriesen and Alt-Oldenburger, Kladruber, and Groningen. Visual identification When identifying t ...

Equine Coat Color
Horses exhibit a diverse array of coat colors and distinctive horse markings, markings. A specialized vocabulary has evolved to describe them. While most horses remain the same coat color throughout life, some undergo gradual color changes as they age. Most horse markings, white markings are present at birth, and the underlying skin color of a healthy horse does not change. Certain coat colors are also associated with specific breeds, such as the Friesian, which is almost exclusively black. 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 continue about some of the details, particularly those surrounding spotting patterns, color sub-shades such as "sooty (gene), sooty" or "flaxen gene, flaxen", and horse markings, markings.

Liver Chestnut
Chestnut is a hair coat color of horses consisting of a reddish-to-brown coat with a mane and tail the same or lighter in color than the coat. Chestnut is characterized by the absolute absence of true black hairs. It is one of the most common horse coat colors, seen in almost every breed of horse. Chestnut is a very common coat color but the wide range of shades can cause confusion. The lightest chestnuts may be mistaken for palominos, while the darkest shades can be so dark they appear black. Chestnuts have dark brown eyes and black skin, and typically are some shade of red or reddish brown. The mane, tail, and legs may be lighter or darker than the body coat, but unlike the bay they are never truly black. Like any other color of horse, chestnuts may have pink skin with white hair where there are white markings, and if such white markings include one or both eyes, the eyes may be blue. Chestnut foals may be born with pinkish skin, which darkens shortly afterwards. Chestnu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
