Question

Answer 1

defines a species as any group of actually or potentially interbreeding species that produce viable offspring.

Step-by-step explanation:

Biological species refers to a group of genetically and physically compatible organisms. These organisms are capable of mating or interbreeding and the offspring that result from this mating, as a rule of thumb, must be valid or fertile.

Hence, species do not only share similar genetic materials (in form of DNA), they must also be physically compatible to mate and the resulting offspring from the mating must be fertile.
