Question

For organisms to be classified as the same species, they must be able to breed with each other and produce _____ offspring.

Answer 1

They must be able to breed and produce fertile offspring.

Answer 2

Fertile

Step-by-step explanation:

Organism belonging to different species can mate but the offspring produced will not have re productivity or fertility.

For example -

When a healthy horse and a healthy donkey mate, they produce mule. Mule is also a healthy species but is a hybrid species of the two and thus infertile.

Therefore, two organisms that belong to the same species must mate together in order to produce offspring with high re-productivity, fertility and viability.
