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

  1. Syntype

  2. Isotype

  3. Neotype

  4. Mesotype
Reveal answer Fill a bubble to check yourself
B Correct answer
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 

  1. Mesotypes

  2. Meotypes

  3. Syntypes

  4. Isotypes
Reveal answer Fill a bubble to check yourself
D Correct answer
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'

  4. Magnifera indica
Reveal answer Fill a bubble to check yourself
B Correct answer
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'.

  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.

Which of the following has correct specific epithet?

  1. Indica mangifera

  2. Leo Panthera

  3. Canis familiaris

  4. Ascaris

  • 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'.

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'.
