Question:
Why are mules and hennas sterile?

Replies:
Because they are hybrid animals. In other words, their parents were separate species. Mules are the result of mating between horses and donkeys. Usually different species can't mate, but if they are successful, their offspring usually can't reproduce themselves. There are exceptions to every rule especially in science and there are instances where hybrids can reproduce, such as matings between wolves and closely related dogs.
