If mules are sterile and require the difficult process of mating a horse with a donkey, why do it?

The direction of the cross significantly impacts the resulting animal due to biological and genetic factors: Horse Mating Donkey

The story of a horse mating with a donkey is not one of romance in the human sense, but rather a story of biology, history, and the fascinating quirks of genetics. It is a tale as old as agriculture itself, centered on the creation of one of the most enduring work animals in history: the mule. If mules are sterile and require the difficult

When a horse and a donkey mate, the resulting hybrid is either a mule (male donkey and female horse) or a hinny (male horse and female donkey), both of which are usually sterile due to having 63 chromosomes [23, 24, 25, 27, 28]. While mules are more common and known for hybrid vigor, both types display a mix of physical traits and distinct vocalizations [25, 26].

: A male may perform a "lip curl" (flehmen response) after sniffing the female to detect pheromones that indicate she is ready to breed.

While extremely rare (roughly 1 in 10 million), female mules (mollies) have occasionally produced offspring when mated with a purebred stallion or jack. Documented cases exist in China and Morocco, but these are genetic anomalies.
