A mule is the offspring resulting from the mating of a male donkey with a female horse, or mare. When the 'opposite' pairing of the parents' genders occurs; that is, the mating of a male horse, or stallion, with a female donkey, known as a "jenny" the resulting offspring is more appropriately referred to as a "hinny". The characteristics of a mule versus a hinny are indeed different, as is found in other crossbred animals where the parents' gender has such an effect with one notable example being the difference between a tigon, or a liger, each the offspring of a tiger and lion pair.
