Grullo
Grulla or grullo, also called blue dun, gray dun or mouse dun, is a equine coat color, color of horses in the dun (color), dun family, characterized by tan-gray or mouse-colored hairs on the body, often with shoulder and dorsal stripes and black barring on the lower legs. In this coloration, each individual hair is mouse-colored, unlike a roan (horse), roan, which is composed of a mixture of dark and light hairs. The several shades of grulla are informally referred to with a variety of terms, including black dun, blue dun, slate grulla, silver grulla or light grulla, silver dun, or lobo dun. Silver grulla may also refer to a grullo horse with silver dapple, regardless of shade. In the Icelandic horse, the grulla color is called gray dun, in the Highland pony it is called mouse dun, and in the Norwegian Fjord horse, ''grå'' or ''gråblakk'' (literally, "gray dun"). The word "grulla" in Spanish means crane (bird), crane. Because of the origin of the name, some people will refer to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tarpan
The term tarpan (''Equus ferus ferus'') refers to free-ranging horses of the Russian steppe from the 18th to the 20th century. It is generally unknown whether those horses represented genuine wild horses, feral domestic horses or hybrids. The last individual believed to be a tarpan died in captivity in the Russian Empire during 1909. Beginning in the 1930s, several attempts were made to develop horses that looked like tarpans through selective breeding, called " breeding back" by advocates. The breeds that resulted included the Heck horse, the , and a derivation of the Konik breed, all of which have a primitive appearance, particularly in having the grullo coat colour. Some of these horses are now commercially promoted as "tarpans", although such animals are only domestic breeds and not the wild animal themselves. Name and etymology The name "tarpan" or "tarpani" derives from a Turkic language (Kazakh or Kyrgyz) name meaning "wild horse". The Tatars and the Cossacks disting ...

Roan (horse)
Roan is a horse coat color pattern characterized by an even mixture of colored and white hairs on the body, while the head and "points"—lower legs, mane, and tail—are mostly solid-colored. Horses with roan coats have white hairs evenly intermingled throughout any other color. The head, legs, mane, and tail have fewer scattered white hairs or none at all. The roan pattern is dominantly inherited, and is found in many horse breeds. While the specific mutation responsible for roan has not been exactly identified, a DNA test can determine zygosity for roan in several breeds. True roan is always present at birth, though it may be hard to see until after the foal coat sheds out. The coat may lighten or darken from winter to summer, but unlike the gray coat color, which also begins with intermixed white and colored hairs, roans do not become progressively lighter in color as they age. The silvering effect of mixed white and colored hairs can create coats that look bluish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dun Gene
The dun gene is a dilution gene that affects both red and black pigments in the equine coat color, coat color of a horse. The dun gene lightens most of the body while leaving the mane (horse), 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 equine coat color genetics, 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 (horse color), chestnut base may appear a light tan shade, and those with black horse, 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 ...

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.

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 or "red" coat. When dominant (E), a horse is 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 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 gene is the cream gene, responsible for pa ... [...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. Black is a relatively uncommon coat color, and it is not uncommon to mistake dark chestnuts or bays for black. True 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 often will determine color. Black horses that do not sun bleach are called "non-fading" blacks. Some breeds of horses, such as the Friesian horse, Murgese and Ariegeois (or Merens), are almost exclusively black. Black is also common in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heck Horse
The Heck horse is a horse breed that is claimed to resemble the tarpan (''Equus ferus ferus''), an extinct equine. The breed was created by the German zoologist brothers Heinz Heck and Lutz Heck in an attempt to breed back the tarpan. Although unsuccessful at creating a genetic copy of the extinct form, they developed a breed with grullo coloration and primitive markings. Heck horses were subsequently exported to the United States, where a breed association was created in the 1960s. Breed characteristics Heck horses are dun or grullo (a dun variant) in color, with occasional white markings. The breed has primitive markings, including a dorsal stripe and horizontal striping on the legs. Heck horses generally stand between tall. The head is large, the withers low, and the legs and hindquarters strong. The hooves are strong, often not needing shoeing. The gait of the Heck horse is high stepping, which makes them comfortable to ride and which is considered attractive while b ...

Gray (horse)
A gray horse (or grey horse) has a coat color characterized by progressive depigmentation of the colored hairs of the coat. Most gray horses have black skin and dark eyes; unlike some equine dilution genes and some other genes that lead to depigmentation, gray does not affect skin or eye color. Gray horses may be born any base color, depending on other color genes present. White hairs begin to appear at or shortly after birth and become progressively more prevalent as the horse ages as white hairs become intermingled with hairs of other colors. Graying can occur at different rates—very quickly on one horse and very slowly on another. As adults, most gray horses eventually become completely white, though some retain intermixed light and dark hairs. The stages of graying vary widely. Some horses develop a dappled pattern for a period of time, others resemble a roan with more uniform intermixing of light and dark hairs. As they age, some gray horses, particularly those hetero ...

Primitive Markings
Primitive markings are a group of hair coat markings and qualities seen in several equine species, including horses, 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 coat color family. All dun horses possess at least the 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 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 horse, "bred back" to resemble the now-extinct tarpan The term tarpa ...

Konik
The Konik or Polish Konik, pl, konik polski, is a Polish breed of pony. There are semi-feral populations in some regions. They are usually mouse dun or striped dun in color. The Bilgoray, pl, konik biłgorajski, of south-eastern Poland is a sub-type of the breed influenced by Arab and Thoroughbred blood; it is close to extinction. The extinct Sweyki or Schweike sub-type of East Prussia contributed to the development of the Trakehner. The word "konik" means 'small horse'. It may be used in a wider sense to describe the Polish Konik and other similar breeds, among them the Hutsul of the Carpathian Mountains, the Polesian of Belarus and the Žemaitukas of Lithuania. Etymology The Polish word ''konik'' (plural ''koniki'') is the diminutive of ''koń'', the Polish word for "horse" (sometimes confused with ''kuc, kucyk'' meaning "pony"). It means 'small horse'. History The Konik is a Polish horse breed descending from very hardy horses from the Biłgoraj region. Thes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Horse
A feral horse is a free-roaming horse of domesticated stock. As such, a feral horse is not a wild animal in the sense of an animal without domesticated ancestors. However, some populations of feral horses are managed as wildlife, and these horses often are popularly called "wild" horses. Feral horses are descended from domestic horses that strayed, escaped, or were deliberately released into the wild and remained to survive and reproduce there. Away from humans, over time, these animals' patterns of behavior revert to behavior more closely resembling that of wild horses. Some horses that live in a feral state but may be occasionally handled or managed by humans, particularly if privately owned, are referred to as " semi-feral". Feral horses live in groups called a ''herd'', ''band'', ''harem,'' or ''mob''. Feral horse herds, like those of wild horses, are usually made up of small harems led by a dominant mare, containing additional mares, their foals, and immature horses o ...
