Equus caballus (horse) horse Lineage: Eukaryota[13882]; Metazoa[6614]; Chordata[3172]; Craniata[3144]; Vertebrata[3144]; Euteleostomi[3111]; Mammalia[848]; Eutheria[674]; Laurasiatheria[325]; Perissodactyla[11]; Equidae[4]; Equus[4]; Equus caballus[1]

Equus caballus, the domestic horse, has played a crucial role in the development of human civilization. It has economic importance throughout the world and is used for transportation, work and entertainment. It is a model organism for research on biomechanics and exercise physiology. The genome sequence will facilitate the identification of genes More...that are involved in mammalian evolution and help us to better understand the genetic basis of diseases common to both humans and horses, such as allergies and arthritis.
The Equus caballus genome is distributed over 31 autosomes and two sex chromosomes. Less...
