Mouflon scientific literature as separate species, "Ovis musimon" and "Ovis orientalis". The mouflons are also sometimes treated as a subspecies of the domestic sheep, "Ovis aries", named with the same subspecific epithet as above: "O. a. musimon", "O. a. ophion", etc. Based on comparison of mitochondrial cytochrome b gene sequences, three groups of sheep ("Ovis") have been identified: Pachyceriforms of Siberia (snow sheep) and North America (bighorn and Dall sheep), Argaliforms (argali) of Central Asia, and Moufloniforms (urial, mouflon, and domestic sheep) of Eurasia. However, a comparison of the mitochondrial DNA control region (CR) found that two subspecies of urial, "Ovis
Soay sheep rump patch and/or white patch under the chin (referred to as the Mouflon or wild pattern). Occasionally white markings on the face and/or body and legs occur. Rarely self-colored (solid color with no markings) black or tan individuals are seen. This breed has extremely fine fleece and, in contrast to mouflon, the inner fleece is highly developed and it is difficult to distinguish an outer coat. This is a clear indication that the Soay are indeed the product of a domesticated breed in prehistoric times. The breed also lacks the flocking instinct of many breeds. Attempts to work them using
