Mules and hinnies

Perhaps the most widespread and useful of hybrids are mules (from a male donkey and a female horse) and hinnies (from a male horse and a female donkey). Reputed for their hard work and strength despite their medium size, mules are dependable and often exhibit higher intelligence then their purebred parents. All male mules and most female mules are infertile, so their continued existence depends entirely on human intervention.
