Question

As a practical definition of species, what is/are the criteria mandate to consider two organisms belonging to the same species?

• A. The organisms have the same parents
• B. The organisms can interbreed
• C. The organisms can produce fertile offsprings
• D. The organisms' offsprings can produce fertile offsprings.

Answer 1

The correct option is D

The organisms' offsprings can produce fertile offsprings.

For two organisms to be belonging to the same species coming from the same parents, interbreeding and even producing offsprings don't ensure it. Because a horse and a donkey can reproduce to form a mule but horse and donkey don't belong to the same species.
