Hinny to the action of imprinted genes." A male hinny is properly called a "horse hinny", and a female hinny is properly called a "mare hinny", though in British English both female hinnies and female donkeys are sometimes called "jennets". Hinnies are difficult to obtain because of the differences in the number of chromosomes of the horse and the donkey. A donkey has 62 chromosomes, whereas a horse has 64. Hinnies, being hybrids of those two species, have 63 chromosomes and are sterile. The uneven number of chromosomes results in an incomplete reproductive system. According to the ADMS: "The equine hybrid
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. Large groups of primates are called "troops”, which are characterized by complex intratroop politics and competition. 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
