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
European mouflon hairy coat, the rams are fox red-brown in the summer, usually with a whitish saddle patch, the ewes are brownish. Both sexes are darker in winter. The rams have helix-shaped horns up to 80 cm long; females have no horns on Sardinia, but on Corsica they have smaller horns that are slightly curved towards the rear. As an animal whose ancestors used to live in open terrain above the tree line, the eyesight of the mouflon is well developed. Its laterally-located eyes allow the mouflon to scan a wide arc without turning its head. In older rams, the field of
