A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. A domestic animal of unknown ancestry, where the breed status of only one parent or grandparent is known, may also be called a crossbreed though the term "mixed breed" is technically more accurate. Outcrossing is a type of crossbreeding used within a purebred breed to increase the genetic diversity within the breed, particularly when there is a need to avoid inbreeding .
36-732: The Anglo-Arabian , also known as the Anglo-Arab , is a horse breed that originated in France by cross-breeding a Thoroughbred with an Arabian . The Anglo-Arabian has origins tracing back to the Limousin Horse . It was officially recognized by Emperor Louis Philippe I and produced by the Haras National du Pin . The Anglo-Arabian has long legs, a refined head, larger hindquarters, and are most commonly seen in gray , bay , or chestnut . To be recognized as an Anglo-Arabian with
72-404: A draft animal that pushes against a load . The withers in horses are formed by the dorsal spinal processes of roughly the 3rd through 11th thoracic vertebrae , which are unusually long in this area. Most horses have 18 thoracic vertebrae. The processes at the withers can be more than 30 centimetres (12 in) long. Since they do not move relative to the ground as the horse's head does,
108-469: A "breed" rather than a crossbreed. There are disadvantages to creating designer crossbreeds, notably the potential that the cross will be of inferior quality or that it will not produce as consistent a result as would breeding purebred animals. For example, the Poodle is a frequent breed used in creation of designer crossbreeds, due to its non-shedding coat, but that trait does not always breed true when it
144-514: A 75/25 cross, or a BC1 or F1b " backcross ." The breeding of two crossbreeds of the same combination of breeds, creating an F2 cross, an animal that is still a 50–50 cross, but it is the second filial generation of the combination. An F2 cross bred to an F2 cross creates an F3 cross. Similarly, an F2 animal bred to an F1 animal creates an F2b backcross. F3 crosses and greater are called "multi-generational" crosses. In dog breeding, three generations of reliable documented breeding can be considered
180-508: A mix of characteristics from both, periodically producing a fleeced llama. The results are increasingly unpredictable when both parents are crossbreeds, with possibility of the offspring displaying characteristics of a grandparent, not obvious in either parent. Dogs: A crossbred dog is a cross between two (sometimes more) known breeds, and is usually distinguished from a mixed-breed dog , which has ancestry from many sources, some of which may not be known. Crossbreeds are popular, due to
216-465: A mutt or a mongrel , its entire pedigree is known to descend from specific known animals. While the term is best known when applied to certain dog crossbreeds , other animals such as cattle, horses, birds and cats may also be bred in this fashion. Some crossbred breeders start a freestanding breed registry to record designer crossbreds, other crossbreds may be included in an "appendix" to an existing purebred registry. either form of registration may be
252-501: A specific environment, and are crossed with purebred bulls from another environment to produce a generation having traits of both parents. Sheep: The large number of breeds of sheep, which vary greatly, creates an opportunity for crossbreeding to be used to tailor production of lambs to the goal of the individual stockman. Llamas: Results of crossbreeding classic and woolly breeds of llama are unpredictable. The resulting offspring displays physical characteristics of either parent, or
288-500: A true-breeding population and have a closed stud book . Other types of recognized crossbreeding include that within the American Quarter Horse , which will register horses with one Thoroughbred parent and one registered Quarter Horse parent in the "Appendix" registry, and allow such animals full breed registration status as Quarter Horses if they meet a certain performance standard. Another well-known crossbred horse
324-420: A yak and an American bison ). The Incas recognized that hybrids of Lama glama (llama) and Vicugna pacos (alpaca) resulted in a hybrid with none of the advantages of either parent. At one time it was thought that dogs and wolves were separate species, and the crosses between dogs and wolves were called wolf hybrids. Today wolves and dogs are both recognized as Canis lupus , but the old term "wolf hybrid"
360-403: Is also important in jumping, as the shoulder must rotate back for the horse to bring its foreleg parallel to the ground, which will then raise the animal's knees upward and get the lower part of the forelegs out of the way. Therefore, the withers have a direct impact on one of the most important points of conformation : the shoulder. In dogs , the height of the withers is often used to determine
396-559: Is now extinct, the Limousins were the predecessor of the Anglo-Arabians and significantly influenced the creation of this breed. In the 1750s, breeders from Normandy , France, bred Syrian imported Arabians with native thoroughbred mares. There is limited documentation on their breeding of the Anglo-Arabians, but the breeders are credited with the first traceable origins as the offspring of these mares were later used to produce

#1732771824867432-431: Is often called a "moggie". A horse of unknown bloodlines is called a grade horse . A designer crossbreed or designer breed is a crossbred animal with purebred parents, usually registered with a breed registry , but from two different breeds . These animals are the result of a deliberate decision to create a specific crossbred animal. Less often, the animal may have more than two pure breeds in its ancestry, but unlike
468-415: Is part of a designer cross. Also, because breeders of crossbred animals may be less careful about genetic testing and weeding out undesirable traits, certain deleterious dominant genes may still be passed on to a crossbreed offspring. In an F2 cross, recessive genetic traits may also return if the parent animals were both carriers of an undesired trait. Withers Withers are the ridge between
504-423: Is still used. A mixed-breed animal is defined as having undocumented or unknown parentage, while a crossbreed generally has known, usually purebred parents of two distinct breeds or varieties. A dog of unknown parentage is often called a mixed-breed dog, "mutt" or " mongrel ." A cat of unknown parentage is often referred to as a domestic short-haired or domestic long-haired cat generically, and in some dialects
540-484: Is taller than the average Arabian but just below the height of a thoroughbred. Their body is sturdily built, similar to the thoroughbred, with refined heads that showcase their Arabian lineage. They have a deep chest, round hindquarters, prominent withers , and lengthy legs. The most common colors for the Anglo-Arabian are chestnut , bay , or gray . The Arabian Horse Association accepts any color and height for
576-479: Is the Anglo-Arabian , which may be produced by a purebred Arabian horse crossed on a Thoroughbred, or by various crosses of Anglo-Arabians with other Anglo-Arabians, as long as the ensuing animal never has more than 75% or less than 25% of each breed represented in its pedigree. A hybrid animal is one with parentage of two separate species, differentiating it from crossbred animals, which have parentage of
612-535: Is the process of breeding such an organism. It can be beneficially used to maintain health and viability of organisms. However, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism. Cats: The many newly developed and recognized breeds of domestic cat are crossbreeds between existing, well-established breeds (sometimes with limited hybridization with some wild species), to either combine selected traits from
648-627: The Arabian Horse Association , the horse must have at least 25% Arabian blood. There are no color or height restrictions to be registered. Due to its lineage and physique, the Anglo-Arabian is utilized for sports-related activities such as dressage , show jumping , endurance , and cross-country . Genetic diseases are possible as the foal is likely to inherit a combination of both parent genes. Genetic testing will help limit fetal DNA exposure and ensure knowledgeable breeding. The most common genetic diseases associated with
684-484: The foundation stock , or propagate a rare mutation without excessive inbreeding . However, some nascent breeds such as the Aegean cat are developed entirely from a local landrace population. Most experimental cat breeds are crossbreeds. Cattle: In cattle, there are systems of crossbreeding. In many crossbreeds, one animal is larger than the other. One is used when the purebred females are particularly adapted to
720-404: The shoulder blades of an animal, typically a quadruped . In many species, this ridge is the tallest point of the body. In horses and dogs, it is the standard place to measure the animal's height. In contrast, cattle are often measured to the top of the hips. The term (pronounced / ˈ w ɪ ð . ər z / ) derives from Old English wither ("against'), because the withers are the part of
756-421: The warmblood breeds used in the sport horse disciplines, usually registered in an open stud book by a studbook selection procedure that evaluates conformation, pedigree and, in some animals, a training or performance standard. Most warmblood breeds began as a cross of draft horse breeds on Thoroughbreds , but have, in some cases, developed over the past century to the point where they are considered to be

#1732771824867792-473: The Anglo-Arabian lineage include Severe Combined Immunodeficiency , Cerebellar Abiotrophy , Lavender Foal Syndrome , and Occipitoatlantoaxial Malformation. The Limousin horse was a breed that originated from the region of Limousin in France during the Medieval times . They were created by breeding French native mares with imported English Thoroughbreds and a sprinkle of Arabian blood. Although this breed
828-609: The French defeated the Muslims in the Battle of Tours . The service also attempted to crossbreed in the opposite direction, where Arabian mares bred with English sires, but found that the foal was less desirable as the size of the mother’s uterus affects the adult size of the foal. In 1880, the Anglo-Arabian breed criteria formally established that a horse only needed 25% Arabian blood to be considered an Anglo-Arabian. As long as they have
864-463: The battlefield. On the other hand, thoroughbreds were primarily bred for racing and show jumping due to their athleticism. Combining these two breeds resulted in the Anglo-Arabian, which is an ideal breed for sports-related activities such as show jumping, cross-country , endurance , or dressage . The best examples of this breed inherit the Arabian's refinement, structure, and endurance as well as
900-451: The belief that they have increased vigor without loss of attractiveness of the dog. Certain planned crossbreeding between purebred dogs of different breeds are now widely known as "designer dogs" and can produce puppies worth more than their purebred parents, due to a high demand. Horses: Crossbreeding horses is often done with the intent of ultimately creating a new breed of horse. One type of modern crossbreeding in horses created many of
936-430: The breed, but the association requires photos of their coloring to be submitted for registration. Breeding Arabians and thoroughbreds comes with a risk of breed-specific diseases that can be inherited. When breeding Anglo-Arabians, it is vital to prioritize the breed's well-being and genetic health by noting potential health problems. Genetic testing can help identify carriers of these diseases, prevent them from entering
972-454: The breeding stream, and assist breeders in making informed decisions before breeding. By being mindful of these health concerns, breeders can ensure the breed's continued success. The following diseases are autosomal recessive traits that will lead to the death or euthanasia of the affected foal. The Arabian breed was initially developed to be war horses , known for their great stamina, endurance, and intelligence, which aided their riders on
1008-419: The first step in recording and tracking pedigrees in order to develop a new breed. The purpose of creating designer crossbreds is usually one or more of the following reasons: Breeders of designer crossbreds borrow the technical language from hybrid plant breeding: A first generation, 50–50 crossbred is an F1 cross . Subsequent generations may see a purebred animal crossed back on a crossbred, creating
1044-404: The horse are considered in evaluating conformation. Generally, a horse should have well-defined withers, as they are considered an important attachment point for the muscles of the torso. Withers of medium height are preferred, as high withers make it difficult to fit a saddle and are often associated with a narrow chest, and low withers (known as "mutton withers") do not provide a ridge to help keep
1080-493: The horse's pedigree . In 1836, the French National Stud Service, Haras National du Pin , began officially breeding Anglo-Arabians. Their service was responsible for maintaining the breedings for private cooperators, and they were highly selective in picking and breeding the most exceptional candidates. They crossed the imported English Thoroughbred mares with Arabians that remained in the country after
1116-677: The minimum ratio, they can be registered with the Anglo-Arabian Horse Registry of the Arabian Horse Association (AHA) and are eligible to participate in AHA shows. Horses registered with the Arabian Horse Association will be given the breed brand . The size and appearance of the Anglo-Arabian breed mix varies depending on their ancestry, just like other breed mixes. On average, they stand between 15.2 and 16.3 hands (62-67 inches, 158-65 cm) tall, which

1152-524: The officiated Anglo-Arabians. In 1833, Emperor Louis Phillipe I passed an ordinance that led to the creation of the French Studbook. The primary aim of the Studbook was to help establish the breeds of horses suitable for race horsing. The Studbook officially recognized English, Arab, and Anglo-Arab horses as suitable breeds. It also served as a valuable resource for those interested in locating
1188-401: The saddle in place. More importantly, the dorsal spinal processes provide an attachment for the muscles that support the shoulder and neck. Horses do not have a clavicle , so the shoulder can freely rotate backwards. If the vertebrae of the withers are long front-to-back, the shoulder is freer to move backwards. This allows for an increase of stride length. thus increasing the horse's speed. It
1224-404: The same species. Hybrids are usually, but not always, sterile. One of the most ancient types of hybrid animal is the mule , a cross between a female horse and a male donkey . The liger is a hybrid cross between a male lion and female tiger . The yattle is a cross between a cow and a yak . Other crosses include the tigon (between a male tiger and female lion) and yakalo (between
1260-490: The speed and scope of the Thoroughbred. Crossbreed In animal breeding, crossbreeds are crosses within a single species, while hybrids are crosses between different species. In plant breeding terminology, the term crossbreed is uncommon, and no universal term is used to distinguish hybridization or crossing within a population from those between populations, or even those between species. Crossbreeding
1296-442: The withers are used as the measuring point for the height of a horse. Horses are sometimes measured in hands – one hand is 4 inches (10.2 cm). Horse heights are extremely variable, from small pony breeds to large draft breeds. The height at the withers of an average thoroughbred is 163 centimetres (16.0 hands; 5 ft 4 in), and ponies are up to 147 centimetres (14.2 hands; 4 ft 10 in). The withers of
