Equus, horses and donkeys.
Donkeys and horses are not from the same species because of this: In sexual organisms, two organisms belong to the same species if they are able to breed and have fertile offspring. Although horses and donkeys can have mules, they are infertile, so they are two separate species and the mule is a hybrid.
A species is a group of organisms that share similar physical, metabolical and behavioral traits, which can interbreed to make fertile offspring.For example, horses and donkeys can breed to make a mule, but as it is infertile, horses and donkeys are separate species.
Horses and donkeys are considered different species primarily due to their distinct genetic makeup; horses have 64 chromosomes, while donkeys have 62. When they interbreed, they can produce mules (a horse-donkey hybrid), which are typically sterile due to the mismatched chromosome numbers. This sterility prevents mules from reproducing and reinforces the classification of horses and donkeys as separate species. Additionally, they exhibit notable differences in behavior, morphology, and ecology.
