Binomial Nomenclature - Practice Questions & MCQ

• It was given by Carolus Linnaeus ( Philosophia Botanica, 1751). He published names in Species Plantarum. 
• Binomial nomenclature refers to the nomenclature system on the basis of which a scientific name is provided to an organism. 
• This name comprises of two words, the first one is its genus name while the second one is its species name.
•  For example, the scientific name of the bee is Apis indica. Here, Apis is the name of the genus whereas indica is the name of species. 
• Some scientific names have three words also. The third word is the variety name of the organism. E.g. Homo sapiens sapiens. 

Rules of Binomial Nomenclature
To set the rules for naming, there are five codes
ICBN- International code of botanical nomenclature
ICZN- International code of zoological nomenclature
ICBaN- International code of bacteriological nomenclature
ICVN- International code of viral nomenclature
ICNCP- International code of nomenclature for cultivated plants

• The generic name is written first and specific name follows it.
• The generic name starts with a capital letter while specific name starts with a small letter.
• The scientific names are printed in italics. When handwritten, they are underlined.
• No names are recognised prior to those used by Linnaeus in 1753 in Species Plantarum and in 1758 Systema Naturae.
