30-623: The Retuertas or Caballo de las Retuertas is a Spanish breed of horse indigenous to Andalusia . It is found only in the Doñana National Park in the provinces of Huelva and Sevilla , with a conservation herd in the Campanarios de Azaba Biological Reserve in Espeja ( Salamanca Province ) a part of which is the research reserve of the Consejo Superior de Investigaciones Científicas,

60-403: A designer crossbred . For the purposes of this list, certain groups of horses that have an organization or registry that records individual animals for breeding purposes, at least in some nations, but does not clearly fall to either the breed or type categories are listed here. This list does not include organizations that record horses strictly for competition purposes. A "type" of horse is not

90-465: 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

120-514: 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

150-514: A breed but is used here to categorize groups of horses or horse breeds that are similar in appearance ( phenotype ) or use. A type usually has no breed registry , and often encompasses several breeds. However, in some nations, particularly in Europe, there is a recording method or means of studbook selection for certain types to allow them to be licensed for breeding. Horses of a given type may be registered as one of several different recognized breeds, or

180-406: A breed, a crossbreed, or a "type”, depending on the stage of breed recognition. In some cultures and for some competition-sanctioning organizations, a horse that normally matures less than about 145 cm or 14.2  hands (58 inches, 147 cm) when fully grown may be classified as a " pony ". However, unless the principal breed registry or breed standard describes the breed as a pony, it

210-635: A grouping may include horses that are of no particular pedigree but meet a certain standard of appearance or use. Prior to approximately the 13th century, few pedigrees were written down, and horses were classified by physical type or use. Thus, many terms for Horses in the Middle Ages did not refer to breeds as we know them today, but rather described appearance or purpose. These terms included: Many breeds of horse have become extinct , either because they have died out, or because they have been absorbed into another breed: Crossbreeding A crossbreed

240-508: 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

270-465: 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

300-437: A number of " color breed ", sport horse , and gaited horse registries for horses with various phenotypes or other traits, which admit any animal fitting a given set of physical characteristics, even if there the trait is not a true-breeding characteristic. Other recording entities or specialty organizations may recognize horses from multiple breeds, or are recording designer crossbreds . Such animals may be classified here as

330-422: 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 are considered the authority as to whether a given breed is listed as a "horse" or a "pony". There are also

360-634: A preferred color, not color breeds, and include the Friesian horse , the Cleveland Bay , the Appaloosa , and the American Paint Horse . The best-known "color breed" registries that accept horses from many different breeds are for the following colors: The distinction is hotly debated between a standardized breed, a developing breed with an open studbook , a registry of recognized crossbred horses, and

390-501: 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

420-490: 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

450-420: 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"

480-399: 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

510-446: Is listed in this section, even if some or all representatives are small or have some pony characteristics. Ponies are listed in the § Pony breeds section below. If a breed is described as a "pony" by the breed standard or principal breed registry, it is listed in this section, even if some individuals have horse characteristics. All other breeds are listed in the § Horse breeds section above. (Because of this designation by

540-431: 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

570-423: 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

600-472: 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

630-428: Is the stud book limited in any fashion. As a general rule, the color also does not always breed on (in some cases due to genetic impossibility), and offspring without the stated color are usually not eligible for recording with the color breed registry. There are breeds that have color that usually breeds "true" as well as distinctive physical characteristics and a limited stud book. These horses are true breeds that have

660-535: 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

690-506: The Spanish National Research Council . In 2016 it was added to the list of domestic animal breeds with national government recognition. This horse breed –related article is a stub . You can help Misplaced Pages by expanding it . List of horse breeds While there is no scientifically accepted definition of the term "breed", a breed is generally defined as having distinct true-breeding characteristics over

720-480: 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

750-421: 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

780-451: 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

810-433: The breed, particularly when there is a need to avoid inbreeding . 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

840-419: 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

870-430: The preference of a given breed registry, most miniature horse breeds are listed as "horses", not ponies.) There are some registries that accept horses (and sometimes ponies and mules) of almost any breed or type for registration. Color is either the only criterion for registration or the primary criterion. These are called " color breeds ", because unlike "true" horse breeds, there are few other physical requirements, nor

900-404: 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
