Cross-breeds
Different species of Equus can crossbreed, though the ensuing offspring are usually infertile. Hybrids include:
- Mule, a cross between a male donkey and a female horse. Mules are the most common type of hybrid equine and are renowned for their toughness, surefootedness, and working ability.
- Hinny, a cross between a female donkey and a male horse. Considered a less desirable cross than a mule, generally smaller in size and not as hardy.
Any equine with partial zebra ancestry is called a zebroid.
