A complete blueprint of the domestic horse's genetic code has revealed remarkable similarities with humans, say scientists.
Researchers believe the new gene map could increase understanding of diseases in both humans and the animals.
Horses suffer from more than 90 hereditary diseases that are similar to human disorders.
An international team of scientists analysed DNA from an adult female thoroughbred horse named Twilight.
Her genetic code, or genome, was composed of around 2.7 billion 'letters' - slightly more than the domestic dog, but fewer than humans and cows, the team report.
But the Horse Genome Project scientists were surprised to find that horses and humans shared unusually similar chromosomal arrangements.
