Mule A mule is the offspring of a male donkey (jack) and a female horse (mare). Horses and donkeys are different species, with different numbers of chromosomes. Of the two F1 hybrids (first generation hybrids) between these two species, a mule is easier to obtain than a hinny, which is the offspring of a female donkey (jenny) and a male horse (stallion). The size of
Multi-male group more than one adult male, more than one adult female, and offspring. Within Order Primates, it is the most common social group type, with group sizes ranging from 10 to 100 individuals composed of several males, and numerous females and offspring.

Multi-male groups are most common among semi-terrestrial primates such as savanna baboons and macaques, but is also seen in some colobus and New World monkeys. Social lemurs sometimes often live in multi-male groups, and other primate species like chimpanzees live in fission-fusion multi-male
