Mule - online puzzles
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 a mule and work to which it is put depend largely on the breeding of the mule's female parent ( dam ). Mules can be lightweight, medium weight, or when produced from draft horse mares, of moderately heavy weight. Mules are reputed to be more patient, hardy and long-lived than horses, and are described as less obstinate and more intelligent than donkeys.
