Question

Biological concept of species is mainly based on

• A. Reproductive isolation
• B. Morphological features only
• C. Methods of reproduction only
• D. Morphology and methods of reproduction

Answer 1

The correct option is A Reproductive isolation

The biological species concept groups the members of the same species organisms that can potentially interbreed to produce fertile offspring. It groups the individuals on the basis of their reproductive isolation, which in turn maintain the morphological differences among the reproductively isolated individuals of the same habitat. It is not based on methods of reproduction.
