1. Ekpadi: The top six levels of species of organisms are called Ekpadi. For example- Division.
2. Binomial Name: The species name of the organism will be Binomial. The first is the genus name and the second is the species name of that genus. Part of the species name of an organism is derived from the name of a person, the name of a region or place, a characteristic of a plant, etc. For example – Mangifera indica.
3. Polynomial Name: The lower level name of the species of organism will be polynomial. For example, Brassica oleracea var. botrytis.
4. Language of the name: The scientific name of the organism must be Latin or Latinized.
5. Initials: The first letter of the genus name of the organism should be capitalized and all letters including the first letter of the species name should be written in small letter. For example – Oryza sativa.
6. Printing mode: When printing the scientific name of the organism must be italic or roman or bold.
7. Handwriting: When writing the scientific name of the organism by hand, English letters must be used and the genus and species must be underlined separately. For example – Mangifera indica.
8. Validity: Each species shall have a valid name. It must be validly published.
9. Name of originator: The name of the scientist who gives the scientific name of a plant or animal should be appended to the end of the scientific name of the plant or animal. For example, Oryza sativa L.
10. Tautonym: The genus and species parts of an organism’s scientific name may be the same. For example – Catla catla.
11. Type Specimen: Plants or animals used as specimens during scientific nomenclature should be preserved in the laboratory.
12. Name of many promoters: If it happens, scientific name of a species is given many in the same or different countries, according to the principles or priority, the first scientist who submits the documents to the ICBN first will be accepted.
Binomial nomenclature is a very important process in biology. This rule is followed with utmost respect in all areas of biology, including teaching and research.
