Question

In fish, Catla catla the specific name is identical with the generic name, thus it is an example of
A. Antonym
B. Tautonym
C. Synonym
D. Homonym

Answer 1

Hint:-Every organism on the earth is classified and named by a set of rules and those rules are
used by all scientists around the planet, and those named are called scientific names, for example, dog,
The scientific name is Canis familiarus.

Complete step-by-step solution:-1. Scientific names follow some specific set of rules, where scientists used a 2 named system,which is called a binomial naming system.
2. Scientists name animals and plants using a certain system which generally describes the genus
and species of an organism.
3. In the scientific name, there are two words where the first word represents the genus, and the second word represents species.
4. And the writing of scientific names also has some set of rules, where the first-word genus name
should start with a capital letter and the species name with a small letter.
5. One of the examples for this binomial nomenclature is Homo sapiens, which generally we called
as humans.
6. Sometimes the genus of the name can be written in an abbreviated form such as H. sapiens,
where the genus is represented only by the first letter.
7. Some times both parts of the scientific name are spelled as same, for example, Rattus rattus
where the genus name and species name both are same but all other rules for the nomenclature
remains the same, such type of scientific names are called as Tautonyms
8. In the above question, the given scientific name Catla catla is a Tautonym.
So the correct option is B.

Note:-
Tautonym is a binary combination of two generic names, where normally it is not accepted by the international coding, however, it is accepted by the international code of zoological nomenclature, so it
is only accepted in zoological names but not accepted in botanical nomenclature.
