Question

Horses and zebras can be bred to produce a zorse, which is infertile. 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.

Answer 1

Answer:

The correct option is B) Their offspring cannot breed.

Explanation:

Organisms belonging to the same species require the ability to breed and produce fertile offsprings. If two organisms breed to produce infertile offsprings, then they are not considered to belong in the same species. Infertile offsprings do not have the capability to reproduce. The breeding between a horse and a zebra produces zorse, which is sterile. This depicts that both the zebra and horse belong to different species as they cannot produce a fertile offspring.

Answer 2

The species is the smallest unit for the classification. All the species hold a level in the trophic level and that level is known as hierarchy levels.

The horse, zebra, lion all these are the species.

The sexual reproduction between two different species is known as cross-breeding. These species are selected for cross-breeding whose have varieties in populations. The liger, mule are the few examples of cross-breeding.

According to the question, the zebra and the horse are belonged to different species and are not able to reproduce due to reproductive isolation.

With the help of biotechnology, we are able to reproduce the different species, but these species are infertile in nature.

Hence, the correction option is B that is their offspring cannot breed.
