what is trinominal nomrnclature
Answers
In biology, trinomial nomenclature refers to names for taxa below the rank of species. These names have three parts. The usage is different in zoology and botany.
This nomenclature gave the name for sub-species. Some species due to their different habit and habitat showed certain minor changes. This causes the development of sub-species. To differentiate this subspecies, the third name was given to such different races. The sub-species name is written in small letter in handwritten manuscript and italicised in books. e.g. Indian and Pakistani crow-Corvus splendens. Burmese crow-Corvus splendens isolens and Crow of Ceylon-Corvus splendens protegatus.
It includes generic, specific and sub-specific names. Thus it is known as trinomial nomenclature.
In biology, trinomial nomenclature refers to names for taxa below the rank of species. This is different for animals and plants:
» for animals its trinomen. There is only one rank allowed below the rank of species: subspecies.
» for plants see ternary name. There is an indeterminate number of infraspecific ranks allowed below the level of species: subspecies is the highest ranked of these.
