Cloning horses is no longer the alien concept it once was. While still being far from being commonplace, this technology has developed beyond recognition over the past two decades, with cloning and cloned bloodlines now more accessible than ever to British breeders, and playing an important role in genetic preservation. What is a clone? A clone horse is a genetically identical replica of another horse. Horses are typically cloned in order to preserve their valuable bloodlines, often in cases where a superior or highly valuable horse has died or been gelded and therefore is unable to produce offspring. The science is also increasingly being used for the genetic preservation of rare and endangered breeds.
