Horse cloning is the process of obtaining a horse with genes identical to that of another horse, using an artificial fertilization technique. Interest in this technique began in the 1980s. The Haflinger foal Prometea, the first living cloned horse, was obtained in 2003 in an Italian laboratory. Over the years, the technique has improved.
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. Bay is the most common color of horse, [ 2 ] followed by black and chestnut. A change at the agouti locus is capable of turning bay to black, while a mutation at the extension locus can turn bay ...
Champagne is a dominant trait, based on a mutation in the SLC36A1 gene. [1] A horse with either one or two champagne genes will show the effects of the gene equally. However, if a horse is homozygous for a dominant gene, it will always pass the gene on to all of its offspring, while if the horse is heterozygous for the gene, the offspring will not always inherit the color.
G. Ledyard Stebbins. Ann Trommershausen Bowling (June 1, 1943 – December 8, 2000) was an American scientist who was one of the world's leading geneticists in the study of horses, conducting research in the areas of molecular genetics and cytogenetics. [1] She was a major figure in the development of testing to determine animal parentage ...
The horse genome was first sequenced in 2006. The Horse Genome Project mapped 2.7 billion DNA base pairs, [1] and released the full map in 2009. [2] The horse genome is larger than the dog genome, but smaller than the human genome or the bovine genome. [2] It encompasses 31 pairs of autosomes and one sex chromosome pair.
This Thoroughbred stallion (W2/+) has one form of dominant white.His skin, hooves, and coat lack pigment cells, giving him a pink-skinned white coat. Dominant white (W) [1] [2] is a group of genetically related coat color alleles on the KIT gene of the horse, best known for producing an all-white coat, but also able to produce various forms of white spotting, as well as bold white markings.
The leopard complex is a group of genetically related coat patterns in horses. These patterns range from progressive increases in interspersed white hair similar to graying or roan to distinctive, Dalmatian -like leopard spots on a white coat. Secondary characteristics associated with the leopard complex include a white sclera around the eye ...
The history of horse domestication has been subject to much debate, with various competing hypotheses over time about how domestication of the horse occurred. The main point of contention was whether the domestication of the horse occurred once in a single domestication event, or that the horse was domesticated independently multiple times.
