They will belong to either the same family or species.
Populations of the same species can successfully interbreed. Humans are a good example of this happening in the real world.
Not necessarily. Organisms that look different can belong to the same species if they can interbreed and produce fertile offspring. Organisms that look similar can also belong to different species if they are reproductively isolated and cannot interbreed successfully.

Organisms that can interbreed and produce fertile offspring are most likely to belong to the same species. This means that they share similar genetic material and can successfully reproduce with each other.
Species.
A group of organisms that can mate and produce offspring which can themselves mate is called a species.
Organisms that can interbreed and produce fertile offspring belong to the same species classification. Organisms within a species share similar characteristics and can reproduce to create viable offspring.
Groups of similar organisms within a species are called populations. Populations consist of individuals of the same species that can interbreed and share a common geographical location.
If a group of organisms cannot be interbreed, and create fertile offspring, thent hey are separate species. If the can be interbreed, and the offspring can also interbreed, then they are different sub-species, or phases of the same species.
