Final answer:
Morphologically similar organisms that are able to sexually reproduce and produce fertile offspring are called members of the same biological species.
Step-by-step explanation:
Morphologically similar organisms that are able to sexually reproduce and produce fertile offspring are called members of the same biological species.
In general, organisms that share similar physical features and genomes tend to be more closely related than those that do not. Such features that overlap both morphologically and genetically are referred to as homologous structures.
For example, the bones in the wings of bats and birds have homologous structures.
The ability to reproduce in kind is a basic characteristic of all living things.
Genetic information is combined through sexual reproduction and offspring are able to successfully reproduce, ensuring the continuation of a species.
