Mouflon vignei" (or "orientalis") "arkal" and "O. v./o. bochariensis", grouped with two different clades of argali ("Ovis ammon"). The ancestral sheep is presumed to have had 60 chromosomes, as in goats ("Capra"). Mouflon and domestic sheep have 54 chromosomes, with three pairs (1+3, 2+8, 5+11) of ancestral acrocentric chromosomes joined to form bi-armed chromosomes. This is in contrast to the argali and urial, which have 56 and 58 chromosomes respectively. If the urial is as closely related to the mouflons as mitochondrial DNA indicates, then two chromosomes would need to have split during its evolution away from the mouflon (sub)species. In
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
