The genome of horses traced

An international team of scientists has managed to trace and map out the genome of the English racehorse. The Icelandic horse was also discussed in connection with the research.

The conclusions from the research will be published in the magazine Science, but it is assumed that they will show how the horse was trained as a domesticated animal about 4.000 to 6.000 years ago.

The research will also portray the mutual characteristics of the horse and other animals such as hoofed animals, such as goats, buffalos and cattle.

Also, the scientists state that the genome of horses and men are to a considerable degree similar. This knowledge is considered to become helpful in medical science also.

Almost a hundred hereditary illnesses are known among hoses where the symptoms are similar to those tormenting the humankind. “Horses and men are tormented by similar diseases. By finding the other gene carriers responsible for them, it is evident that we will have knowledge on diseases for both kinds which will increase and deepen”, says on of the scientists, Kersin Lindblad-Toh, at the Broad Institution at the MIT University in the United States.

By mapping out the genome, the scientists were able to detect a genome from a grown racing mare, by the name of Twilight, which might be translated into Icelandic as Darkness. The technique they used, showed that 2,7 m billions of pail or sets.

Like mentioned before, the scientists did research on the genomes of other horse breeds. Among which was the Icelandic horse, but also the American cowboy horse, the Andalusian horse, the Arabic horse, Belgian draught horse, the Norse fjord horse and more.

With this the variability of the genetic genome of the different breeds compared, both between breeds and amongst them. The outcome of this is a collection of more than a million pails and variable genetic traits between the respective horse types.

The difference turned out to be more than between different types of dogs but less than the genome of humans and cows.
