Keys for identification are used to identify a particular species of organism. Examples of keys used to identify species include morphological keys, which are based on the physical characteristics of organisms, and biochemical keys, which are based on the biochemical properties of organisms. Other keys that can be used to identify species include DNA sequencing, which is based on the genetic code of organisms, and chemical keys, which are based on the chemical composition of organisms.
