  1. The correct answer is: Their offspring cannot breed.

    Explanation: Horses and zebras are considered separate species primarily because, when they are crossbred, the offspring (zorses) are typically infertile. This is a key concept in biology known as reproductive isolation, which reinforces the classification of different species. While they can mate and produce offspring, the inability of those offspring to reproduce highlights the genetic differences that define them as separate species.
