To which scientific genus do the zebra, domestic horse, and donkey all belong?
Answer
*Equus*
The domestic horse, zebras, and donkeys are all classified under the same scientific genus, *Equus*. This shared classification indicates that these species are evolutionarily closely related, sharing a common ancestor relatively recently in evolutionary terms. This close relation within the same genus is the fundamental biological precondition that allows for successful—though typically sterile—crossbreeding between members of different species within that group, such as between a zebra and a horse. The genus level grouping is higher and broader than the species level designation.
