The Miniature Zebu is a modern American breed of zebuine miniature cattle. A breed association was established in 1991.[3]: 245 [4]

Zebu (Bos taurus indicus), a type of domesticated bovine cattle-like animal found in India, East Africa and China.

The zebu (/ˈziːb(j)uː, ˈzeɪbuː/; Bos indicus), also known as indicine cattle and humped cattle, is a species or subspecies of domestic cattle  originating in South Asia.[4] Zebu, like many Sanga cattle breeds, differ from taurine cattle in the fatty hump on their shoulders, their large dewlap, and their sometimes-drooping ears. They are well adapted to high temperatures and are raised throughout the tropics.

The false zokor (Myospalax aspalax) is a species of rodent in the family Spalacidae. It is found in eastern Khentei and eastern Khingan in Mongolia and in the Onon River basin in Russia.

The Siberian zokor (Myospalax myospalax) is a species of rodent in the family Spalacidae. It is found in Kazakhstan and Russia.

The Chinese zokor (Eospalax fontanierii) is a species of rodent in the family Spalacidae.[2] It is endemic to China, ranging from Qinghai Province eastwards to Beijing in steppe and alpine grasslands. Henri Milne-Edwards first described it in 1867. Eradication programs in the 1990s in Qinghai Province resulted in a population decline to less than a third of the former population. It is considered common and has been assessed as Least Concern by IUCN.[1]

Zokors are Asiatic burrowing rodents  resembling mole-rats. They include two genera: Myospalax and Eospalax. Zokors are native to much of China, Kazakhstan, and Siberian Russia.

In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera.[1] Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species  are.[clarification needed]

The donkey or ass is a domesticated equine. It derives from the African wild ass, Equus africanus, and may be classified either as a subspecies thereof, Equus africanus asinus, or as a separate species, Equus asinus.[1]: 1  It was domesticated in Africa some 5000–7000  years ago,[1]: 2 [2]: 3715 [3] and has been used mainly as a working animal since that time.
