In fish Catla, the specific name is identical with the generic name. It is an example of
(A) Autonym
(B) Tautonym
(C) Synonym
(D) Homonym
Solution
In the biological system, the naming of organisms is known as nomenclature . First the organisms with common characters are identified then they are given names according to their characters and the common term used for this is nomenclature. Nomenclature is done as names are given to plants but those are local names that vary from place to place so nomenclature is done.
Complete answer:
First the identification is done, for nomenclature as it is not possible until the organism is described correctly this step is called as identification. In binomial nomenclature each name has two components The generic name “The specific epithet.”
This system of providing a name with two components is called Binomial nomenclature. This system is given by Carolus Linnaeus. Sometimes generic name and specific name is same as that of Catla catla
Now let us know which option means generic name and specific name are same:-
Autonym :- in binomial nomenclature , when names are automatically created under the international code for botanical nomenclature or algal , fungal , zoological nomenclature is called autonym.
Tautonym :- in binomial nomenclature , when specific and generic names are the same it is called as tautonym. As this condition occurs in Catla catla
Synonym :- when two words mean the same it is termed as synonym for that. As for instance bad and evil means the same so they are synonyms for each other.
Homonym :- when two words have the same spelling. Or same pronunciation but not the same meaning. It is termed as a homonym.
Our required answer is B) Tautonym.
Note: Biological names are usually written in Latin language and always written in italics . The first word in biological name is genus and second is specific epithet. When biologic names are written by hand they are separately underlined . The genus name starts with a capital letter and that of a specific epithet starts with a small letter.
