Mules

Mules are hybrid animals resulting from breeding a male donkey (called a jack) with a female horse (mare). They usually inherit the best qualities of both parents—strength and endurance from the donkey, and size and speed from the horse. Mules are known for their hardiness, intelligence, and surefootedness, making them valuable pack animals and work animals in challenging terrains. They are generally sterile and cannot reproduce. Mules have been used for centuries in agriculture, transportation, and other labor-intensive tasks due to their durability and reliability.
