Received: 9 August 2019; Accepted: 13 August 2019; Published: 20 August 2019 Abstract: The Estonian Native Horse (ENH) is a medium-size pony found mainly in the western islands of Estonia and is well-adapted to the harsh northern climate and poor pastures. The ancestry of the ENH is debated, including alleged claims about direct descendance from the extinct Tarpan. Here we conducted a detailed analysis of the genetic makeup and relationships of the ENH based on the genotypes of 15 autosomal short tandem repeats (STRs), 18 Y chromosomal single nucleotide polymorphisms (SNPs), mitochondrial D-loop sequence and lateral gait allele in DMRT3. -
I . the Color Gene C
THE ABC OF COLOR INHERITANCE IN HORSES W. E. CASTLE Division of Genetics, University of California, Berkeley, California Received October, 27, 1947 HE study of color inheritance in horses was begun in the early days of Tgenetics. Indeed many facts concerning it had already been established earlier, by DARWINin his book on “Variation of Animals and Plants under Domestication.” At irregular inteivals since then, new attempts have been made to collect and classify in terms of genetic factors the records contained in stud books concerning the colors of colts in relation to the colors of their sires and dams. A full bibliography is given by CREWand BuCHANAN-SMITH (19301. By such studies, we have acquired very full information as to what color a colt may be expected to have, when the color of its parents and grandparents is known. This knowledge is empirical rather than experimental in nature. For horses being slow breeding and expensive are rarely available for direct experi- mental study, such as can be made with the small laboratory mammals, mice, rats, rabbits and guinea pigs. We have definite information that color inheritance in horses involves the existence of mutant genes similar to those demonstrated by experimental studies to be involved in color inheritance of other mammals. But the horse genes have been given special names, as they were successively discovered, and it is difficult at present to correlate them with the better known names and geneic symbols used by the experimental breeders. The present paper is an attempt to make such a correlation. Just as in morphological studies comparative anatomy was found useful and still is used to establish homologies between systems of organs, so in mammalian genetics, a comparative study of gene action in the production of coat colors and color patterns may also be of value. -
List of Horse Breeds 1 List of Horse Breeds
List of horse breeds 1 List of horse breeds This page is a list of horse and pony breeds, and also includes terms used to describe types of horse that are not breeds but are commonly mistaken for breeds. While there is no scientifically accepted definition of the term "breed,"[1] a breed is defined generally as having distinct true-breeding characteristics over a number of generations; its members may be called "purebred". In most cases, bloodlines of horse breeds are recorded with a breed registry. However, in horses, the concept is somewhat flexible, as open stud books are created for developing horse breeds that are not yet fully true-breeding. Registries also are considered the authority as to whether a given breed is listed as Light or saddle horse breeds a "horse" or a "pony". There are also 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 is little or no evidence of the trait being a true-breeding characteristic. Other recording entities or specialty organizations may recognize horses from multiple breeds, thus, for the purposes of this article, such animals are classified as a "type" rather than a "breed". The breeds and types listed here are those that already have a Wikipedia article. For a more extensive list, see the List of all horse breeds in DAD-IS. Heavy or draft horse breeds For additional information, see horse breed, horse breeding and the individual articles listed below. -

Official Standard of the French Bulldog General Appearance
Official Standard of the French Bulldog General Appearance: The French Bulldog has the appearance of an active, intelligent, muscular dog of heavy bone, smooth coat, compactly built, and of medium or small structure. Expression alert, curious, and interested. Any alteration other than removal of dewclaws is considered mutilation and is a disqualification. Proportion and Symmetry - All points are well distributed and bear good relation one to the other; no feature being in such prominence from either excess or lack of quality that the animal appears poorly proportioned. Influence of Sex - In comparing specimens of different sex, due allowance is to be made in favor of bitches, which do not bear the characteristics of the breed to the same marked degree as do the dogs. Size, Proportion, Substance: Weight not to exceed 28 pounds; over 28 pounds is a disqualification. Proportion - Distance from withers to ground in good relation to distance from withers to onset of tail, so that animal appears compact, well balanced and in good proportion. Substance - Muscular, heavy bone. Head: Head large and square. Eyes dark in color, wide apart, set low down in the skull, as far from the ears as possible, round in form, of moderate size, neither sunken nor bulging. In lighter colored dogs, lighter colored eyes are acceptable. No haw and no white of the eye showing when looking forward. Ears Known as the bat ear, broad at the base, elongated, with round top, set high on the head but not too close together, and carried erect with the orifice to the front. The leather of the ear fine and soft. -

Special Issue Horse Genetics DIRECTOR’S Message
CENTER FOR EQUINE HEALTH SCHOOL OF VETERINARY MEDICINE • UNIVERSITY OF CALIFORNIA, DAVIS SUMMER 2020 Special Issue Horse Genetics DIRECTOR’S Message s an equine genetics researcher, I am particularly excited to share A this special issue of the Horse Report with you. Inside, you will find a roadmap to many of the currently available equine genetic tests, including the AQHA “five-panel” test, and more. The equine genome sequence was published in 2009, the result of a years- long collaborative effort by the international equine research community. This resource drastically changed how researchers approach equine genetics and accelerated the rate of discovery. Increased availability and affordability allowed the application of advanced molecular tools to equine diseases and traits. As a result, genetic tests are available in a variety of breeds. Most available tests are for simple, Mendelian diseases and traits – those caused by a single gene or locus. Complex diseases and traits likely involve more than one gene and may be influenced by environmental effects. The 2018 release of a new equine genome sequence assembly, coupled with cost reductions that make whole-genome sequencing possible for large numbers of horses, are enabling research in these areas. As an equine geneticist and veterinarian, I am especially interested in applying whole genome sequencing and advanced diagnostic tools to equine precision medicine. This highly individualized approach will focus on early detection and prevention of disease, taking into account both genetic information and environmental factors. The idea is to target individuals based on their clinical condition as well as their unique body chemistry and genetics. -
Programs That Extend the Useful Lives of Horses
PROGRAMS THAT EXTEND THE USEFUL LIVES OF HORSES: Supply and demand — they are the ingredients that form the foundation for near- ly all successful business models. Markets are sound and profitable when there is a healthy balance between the two. The theory holds true for the horse market as well. Often, however, owners may not be aware of the demands that exist for horses that may be “unwanted” by some, but desired by others. The purpose of this chapter is to show some of the many programs already in place by horse breed organizations and other groups, in which horses are needed by participants. From trail riding enthusiasts to horse show exhibitors, people are searching every day for horses that fit their lifestyles and interests. By understanding the activities encouraged by breed organizations, owners of some unwanted horses might find a good fit, and a good market, among people seeking horses for organized shows and rec- reational events. Following is a listing of some of the most popular programs and activities underway today and some true-life stories of unwanted horses that developed into champions. Competitive Horse Shows: Nearly all horse breed associations offer opportunities for friendly competition. Although a horse may be retired or reaching advanced years of maturity, horse shows offer outlets to help keep the horse active and involved. The registries offer several different disciplines with classes ranging from leadline to saddle seat pleasure to barrel racing. A horse owner can often find a way to keep horses involved for a long time in the variety of disciplines offered in the showing world. -

19/07/2018 Page 1 of 9 Genetic Screening Tests Available Symbol
Genetic Screening Tests available Symbol Name Description of variant effects Genetic Disease Testing CA is a neurological disorder that affects the cells in the cerebellum, causing head tremors, ataxia and other effects. Affected horses are more likely to fall and are generally not safe to ride. Symptoms appear from 6 weeks to around 4 months old. CA has been linked to a mutation in the TOE1 Cerebellar CA gene and is a recessive disorder, meaning that a horse must Abiotrophy be homozygous (CA/CA) to be affected. If a horse is a carrier (CA/n), it will not show any clinical signs of CA, but it will pass the variant on to approximately half its offspring. Mating to other carriers should be avoided to prevent the birth of an affected foal. LFS causes neurological dysfunction in foals. The symptoms include seizures, hyperextension of the limbs, neck and back, leg paddling, and inability to stand. As the name suggests, LFS also dilutes to the coat to a pale lavender pink or silver colour. The foal will not improve and will die, so it should be euthanised. LFS is a recessive disorder so two copies of the Lavender Foal defective version of the MYO5A gene must be inherited LFS Syndrome (LFS/LFS) for a foal to be affected. If a horse is a carrier (LFS/n), it will not show any clinical signs of LFS. However, there is a 50% chance it will pass the variant to its offspring, so mating to other carriers should be avoided to prevent the birth of an affected foal. -
