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
Somali wild ass home to eleven Somali Wild Asses, the largest population of Somali Wild Asses in North America. The park received its first herd from the Basel Zoo in 1981. Their first foal was born in 1986. Since then, 49 foals have been born, the most recent being a female born on March 17, 2018. San Diego Zoo Global also works to help save this endangered species in the wild. Domestic donkeys found in Italy are typically descended from the Somali wild ass, as opposed to those from other European countries where domesticated stock are usually descended from the Nubian wild ass.
