Horses and zebras can be bred to produce a zorse, which is sterile. which is most likely the reason zebras and horses are considered separate species? they cannot breed. their offspring cannot breed. they look different from each other. they are found in different habitats.

The correct answer is their offsprings cannot breed.

The horses and zebras have their own specific traits, that is, why they belong to distinct species. The most essential trait of a species is that its members are able to breed with each other to generate fertile offsprings. A horse can breed with other horses, and a zebra can reproduce with other zebras.

When two different species mate, they give rise to a hybrid. The hybrid between the horse and zebra is called zorse. However, the hybrid produced is sterile that suggests they further cannot give rise to any offspring.

The answer is B. Their offspring cannot breed.

That's what they mean by being sterile. They can no longer breed. Nor can the offspring breed.
