Question

What is the role of keys in taxonomy? Illustrate with example.

Answer 1

A key in taxonomy helps in the identification of unknown species of organisms based on contrasting characters. It provides basic characters on the basis of which one can get the taxonomic position of an unknown organism. It is analytical in nature. It is of two types, indented key and bracketed key. Indented key gives a number of choices between two or more characteristics of species. The correct choice is essential for identification. For example, wings absent, body covered by furs, etc.
