Questions Related to nomenclature in classification

If a botanist want to study nomenclature of a similar species, the scientist will study

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. Syntype

  2. Isotype

  3. Neotype

  4. Mesotype

Show answer
Correct Option: B
Explanation:
  1. Syntype: It refers to two or more specimens collected by the author simultaneously of the same species.
    2. Isotype: It is a duplicate of the holotype collected and can be used for studies when holotype is not accessible.
    3. Neotype: It refers to the new specimen collected when the original material is missing.
    So, the correct option is 'Isotype'.

Two similar holotypes are called 

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. Mesotypes

  2. Meotypes

  3. Syntypes

  4. Isotypes

Show answer
Correct Option: D
Explanation:
  • A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described.
  • An isotype is a duplicate of the holotype and is often made for plants, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering.
  • Hence Two similar holotypes are called isotypes
  • So, the correct answer is 'Isotypes'

Which of the following is the correct binomial nomenclature?

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. APIS INDICA

  2. Trypanosoma gambiense

  3. Ficus Bengalensis

  4. Magnifera indica

Show answer
Correct Option: B
Explanation:

The various conventions followed while writing Binomial nomenclature are : 

1. It is conventional to write the first letter of the generic name with a capital and the first letter of the specific name with a small letter.
2. Scientific names must be underlined separately when written by hand.
In printed matter, these names are printed in Italic and underlined when handwritten.
In option A, all the letters are capitalized.
In option B, all conventions are followed.
In option C, the generic name is wrongly capitalized and not written in italics.
In option D, the name is not written in italics.
So, the correct option is 'Trypanosoma gambiense'.

In nomenclature

  1. Both genus and species are printed in italics.

  2. Genus and species may be of same name.

  3. Both in genus and species the first letter is capital.

  4. Genus is written after the species.

Show answer
Correct Option: A
Explanation:
The various conventions followed while writing Binomial nomenclature are : 
1. The first letter of the genus name must be capital and the first letter of the species name must be a small letter.
2. Scientific names must be underlined separately when written by hand.
3. In printed matter, these names are printed in Italic and underlined when handwritten.
So, the correct option is 'Both genus and species are printed in italics'.

In Oryza, sativa stands for 

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. Name of species

  2. Specific nomenclature

  3. Specific epithet

  4. Specific name

Show answer
Correct Option: C
Explanation:
Oryza sativa is the binomial name of rice.
Here, Oryza is genus and sativa represents specific epithet as it distinguishes 'rice' from other members of genus Oryza.
So, the correct option is 'Specific epithet'

Which of the following statements regarding universal rules of nomenclature is wrong?

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. Both the words in a biological name when handwritten are separately underlined.

  2. The first word in the biological name represents the genus.

  3. The first word denoting the genus start with a capital letter.

  4. Biological names are generally Greek and written in italics.

Show answer
Correct Option: D
Explanation:

There are certain rules regarding biological nomenclature like - 

  1. Both the words in a biological name when handwritten are separately underlined.
  2. The first word in the biological name represents the genus.
  3. The first word denoting the genus starts with a capital letter.
Also, biological names are generally in Latin and written in italics.
So, the correct option is 'Biological names are generally Greek and written in italics'.

Which of the following has correct specific epithet?

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. Indica mangifera

  2. Leo Panthera

  3. Canis familiaris

  4. Ascaris

Show answer
Correct Option: C
Explanation:

  • According to rules of binomial nomenclature first word in the scientific name is the generic name (represents genus ) and it starts with capital initial. The second word is specific epithet which starts with a small initial. 
  • Only Option C follows these rules.
  • Note that option A seems like a correct option but it has exchanged a generic name and specific epithet. The correct name for mango is 'Mangifera indica'. 
So, the correct option is 'Canis familiaris'.

Read the statements and identify the incorrect one.

  1. Scientific names are often descriptive.

  2. Scientific names indicate relationship.

  3. Scientific names favour multiple naming.

  4. Scientific names are used all over the world.

Show answer
Correct Option: C
Explanation:

Scientific names do not favor multiple naming as it will create confusion among the scientists over the world. Also, the very first significance of the scientific name is to give a unique single name to each species.

So, the correct option is 'Scientific names favor multiple naming'.

The generic name of mango is 

biology classification of living organisms binomial nomenclature nomenclature of organisms naming of the organisms nomenclature in classification

  1. Mangifera indica

  2. Indica

  3. Mangifera

  4. Indica Mangifera

Show answer
Correct Option: C
Explanation:

The generic name refers to the first part of a binomial. The binomial name is comprised of the generic name and the specific epithet. Accordingly, the generic name is the genus of the species and is written by starting with a capitalized letter. As the binomial name of mango is 'Mangifera indica' where 'Mangifera' represents genus, hence it is the generic name and 'indie' represents specific epithet.

So, the correct option is 'Mangifera'.

Specific epithet is

  1. First word in the scientific name of a species

  2. Second word in the scientific name of a species

  3. Both A and B

  4. None of the above

Show answer
Correct Option: B
Explanation:

  • The first word in the scientific name is the generic name ( represents the genus) and the second word is the specific epithet ( represent species name ). 
  • For example - in Homo sapiens, sapiens is the specific epithet.
So, the correct option is 'Second word in the scientific name of a species'.
