Thoroughbred Breeding Theories
Thoroughbred breeding theories are used by horse breeders in an attempt to arrange matings that produce progeny successful in horse racing. Bloodstock experts also rely on these theories when purchasing young horses or breeding stock. A basic understanding of these theories can also help the racing public understand a horse's theoretical genetic potential. The breeding theories stem from the belief that careful analysis of bloodlines can lend predictability to breeding outcomes. A well-designed mating increases the ''probability'' of the offspring's success, although many other factors also come into play. Many thoroughbred breeding theories are implemented from other animal breeding stock practices, such as the use of inbreeding to "fix a type". Some breeding theories are qualitative, relying on judgement. Quantitative breeding theories usually focus on statistical analysis of the sire and broodmare sires in particular. The best-known classification system for mares was developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoroughbred
The Thoroughbred is a horse breed best known for its use in horse racing. Although the word ''thoroughbred'' is sometimes used to refer to any breed of purebred horse, it technically refers only to the Thoroughbred breed. Thoroughbreds are considered " hot-blooded" horses that are known for their agility, speed, and spirit. The Thoroughbred, as it is known today, was developed in 17th- and 18th-century England, when native mares were crossbred with imported Oriental stallions of Arabian, Barb, and Turkoman breeding. All modern Thoroughbreds can trace their pedigrees to three stallions originally imported into England in the 17th and 18th centuries, and to a larger number of foundation mares of mostly English breeding. During the 18th and 19th centuries, the Thoroughbred breed spread throughout the world; they were imported into North America starting in 1730 and into Australia, Europe, Japan and South America during the 19th century. Millions of Thoroughbreds exist today, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplotype
A haplotype ( haploid genotype) is a group of alleles in an organism that are inherited together from a single parent. Many organisms contain genetic material ( DNA) which is inherited from two parents. Normally these organisms have their DNA organized in two sets of pairwise similar chromosomes. The offspring gets one chromosome in each pair from each parent. A set of pairs of chromosomes is called diploid and a set of only one half of each pair is called haploid. The haploid genotype (haplotype) is a genotype that considers the singular chromosomes rather than the pairs of chromosomes. It can be all the chromosomes from one of the parents or a minor part of a chromosome, for example a sequence of 9000 base pairs. However, there are other uses of this term. First, it is used to mean a collection of specific alleles (that is, specific DNA sequences) in a cluster of tightly linked genes on a chromosome that are likely to be inherited together—that is, they are likely to be con ...

Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcrossin ...

Penelope (horse)
Penelope (1798–1824) was a British Thoroughbred racehorse. She won sixteen of her twenty-four races, including two Oatlands Stakes, the Jockey-Club Plate and she beat Oaks and Derby winner Eleanor. She was bred and owned by Augustus FitzRoy, 3rd Duke of Grafton. After retiring from racing she became an influential broodmare, foaling Derby winners Whalebone and Whisker and 1000 Guineas winner Whizgig. Background Penelope was a bay filly bred by Augustus FitzRoy, 3rd Duke of Grafton, and foaled in 1798. She was sired by Claret Stakes winner Trumpator, who after retiring from racing became British Champion sire in 1803. Amongst his other progeny were Champion sire Sorcerer and Epsom Derby winner Didelot. Penelope's dam, Prunella, was a top broodmare and a daughter of the undefeated Highflyer. Prunella won three races, including a Sweepstakes of 200 guineas each at Newmarket. She also foaled Derby winner Pope and Oaks winner Pelisse. All of Prunella's daughters who liv ...

Racehorse Penelope
Horse racing is an equestrian performance sport, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity. Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping. While horses are sometimes raced purely for sport, a major part of horse racing's interest and economic importance is in the gambling associated with i ...

La Troienne
La Troienne (1926–1954) was one of the most famous and influential Thoroughbred broodmares in twentieth century America. She produced 10 winners including two Hall of Fame inductees while at stud, while her daughters in turn produced many notable offspring. In 2000, pedigree expert Janeen Oliver designated her as the taproot of family 1-x, a designation that was implemented by the Pedigree Online Thoroughbred Database in 2003. Recent matrilineal descendants include 2003 Horse of the Year Mineshaft, Japanese Triple Crown winner Contrail (2020), Kentucky Derby winners Smarty Jones (2004) and Super Saver (2010), Belmont Stakes winner Essential Quality (2021), and Sussex Stakes winner Alcohol Free (2021). She was a bay filly born in 1926 in France, and was sired by the French stallion Teddy. Her dam was the winner Helene de Troie, by imported British stallion Helicon. Her breeder and first owner was Marcel Boussac.Ahnert, Rainer L. (editor in chief), "Thoroughbred Breeding of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morel (horse)
Morel (1805 – after 1830) was a British Thoroughbred racehorse and broodmare who won the classic Oaks Stakes at Epsom Downs Racecourse in 1808. In a racing career which lasted from April 1808 until July 1812 the mare ran twenty-seven times and won fourteen races. She was mainly campaigned at Newmarket Racecourse, running against some of the best horses of the era in match races and frequently carrying large weights in handicaps. Unlike many champions of the early 19th century, she was particularly effective at shorter distances, recording many of her successes over a mile or less. After her retirement from racing, Morel became a highly successful and influential broodmare, whose direct descendants have won numerous major races in Europe, North America, Japan and Australasia. Background Morel was a chestnut mare officially bred by her owner Augustus FitzRoy, 3rd Duke of Grafton (1735–1811), the former Prime Minister of Great Britain at his stud at Euston Hall in Suffo ...

Australian Stud Book
The ''Australian Stud Book'' (ASB), is the body responsible for ensuring the integrity of Thoroughbred breeding in Australia. Australia is the second-largest Thoroughbred breeding country in the world behind the US. The principal functions of the ASB include identification procedures along with DNA testing of mares and foals and the recording of a mare’s progeny and stallion statistics. In 2003 the ASB introduced microchips for foals, which is the most secure means of horse identification when and combined with freeze branding, provides racing officials with the most dependable identification system in the world. The ASB regularly produces printed Stud Books. These books are now over 3,000 pages, with volume 42 of the ASB containing the breeding records of 43,000 mares and 70,000 of their named offspring. The ASB also controls the comprehensive online database which contains the records of over 860,000 horses. This database includes every Australian foal born since 1972 and in ...

Weatherbys
The Weatherbys Group is a UK conglomerate involved in a wide range of activities largely within banking and horse racing. The original business was founded by James Weatherby in 1770. History James Weatherby was appointed to serve the Jockey Club as its secretary and stakeholder in 1770. He was an able and entrepreneurial man and over the next 25 years laid strong foundations for the business. Under his aegis, his first racing calendar was published in 1773, followed, in 1791, by the publication of The General Stud Book, a definitive record of the pedigrees of approximately 400 horses which became the foundation for all thoroughbred bloodstock worldwide. He was assisted in this by his nephew, whose work on racehorse pedigrees dovetailed neatly with James's racing work. For the next 250 years, Weatherbys has continued in the role of administrators to the Jockey Club. Today, every data detail relating to horses, owners, trainers, jockeys, stable employees and races is processed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Stud Book
The ''American Stud Book'' is the stud book for the Thoroughbred horse in the United States. It was founded by Sanders Bruce, with assistance from his brother B. G. Bruce.Montgomery ''Thoroughbred'' p. 162 In 1896, The Jockey Club bought out Bruce and assumed publication of the book, which it has continued to the present.Montgomery ''Thoroughbred'' p. 174 The ''American Stud Book'' was first published, as volume one, in 1868, covering the first part of the alphabet from A to K. In 1873, a revised volume one and a second volume were published, with the new volume one covering A through L.Harrison ''Background of the American Stud Book'' pp. 56-57 Bruce continued publishing the volumes, but a fire in his offices right before volume five was published put him in financial difficulty, and he then entered into a legal fight with The Jockey Club over the right to publish the ''American Stud Book'', which was finally settled in 1896 when The Jockey Club bought the ''American Stud Book'' f ...

Epsom Oaks
The Oaks Stakes is a Group 1 flat horse race in Great Britain open to three-year-old fillies. It is run at Epsom Downs over a distance of 1 mile, 4 furlongs and 6 yards (2,420 metres), and it is scheduled to take place each year in late May or early June. It is the second-oldest of the five Classic races, after the St Leger. Officially the Cazoo Oaks, it is also popularly known as simply The Oaks. It has increasingly come to be referred to as the Epsom Oaks in both the UK and overseas countries, although 'Epsom' is not part of the official title of the race.) It is the third of Britain's five Classic races to be held during the season, and the second of two restricted to fillies. It can also serve as the middle leg of the Fillies' Triple Crown, preceded by the 1000 Guineas and followed by the St Leger, although the feat of winning all three is rarely attempted.

Foundation Bloodstock
Foundation bloodstock or foundation stock refers to animals that are the progenitors, or foundation, of a breed or of a given bloodline within such. Many modern breeds can be traced to specific, named foundation animals, but a group of animals may be referred to collectively as foundation bloodstock when one distinct population (including both landrace breeds or a group of animals linked to a deliberate and specific selective breeding program) provides part of the underlying genetic base for a new distinct population. Terminology The terms for foundation ancestors differ by sex, most commonly "foundation sire" for the father and "foundation dam" for the mother. Depending upon the species in question, more specialized terms may be used, such as ''foundation mare'' for female horses, ''foundation queen'' for female cats, or ''foundation bitch'' for female dogs. The offspring of genetically dissimilar parents or stock, whether of different species or different breeds are technica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
