Introduction to binomial nomenclature :
Binomial nomenclature is a system of naming the organisms. Linnaeus established the practice of binomial nomenclature where each organism is denominated by a name composed of two parts, hence, the term “binomial”.
Rules of binomial nomenclature :
Following are the rules of binomial nomenclature:
1. Each organism is given only one name consisting of two words- generic name and the specific epithet.
2. These names are in latin and italicized.
3. The generic name starts with a capital letter and the specific epithet starts with a small letter.
4. Both the words are underlined separately when handwritten and are printed in italics. This indicates their latin origin.
Example of mango :
The correctly written scientific name of mango is Mangifera indica. This is because it follows the system of binomial nomenclature. The other option, Mangifera Indica, is incorrect because the first letter of the species is capital (Indica) (which is violating the rule).
