| Position in name | First word | Second word |
| What it names | The genus | The species part |
| First letter | Capital letter | Small letter |
| Example (Mangifera indica) | Mangifera | indica |
| Shared by many species? | Yes (a genus has many species) | No (separates species in a genus) |
The generic name IS the genus. It is the first word in a scientific name. For example, in Mangifera indica, the word Mangifera is the generic name and it tells you the genus. So 'generic name' and 'genus name' mean the same thing. NEET often swaps these two words in options to confuse you, so remember: generic = genus = first word.
The genus (generic name) always comes FIRST. The specific epithet (the species part) comes SECOND. In the 2023 NEET question, this exact order was tested: X (first) = Generic name, Y (second) = Specific epithet. If an option puts specific epithet first, it is wrong.
They are closely linked but not identical. The specific epithet is only the SECOND word by itself (like 'indica'). The full species name needs BOTH words together (Mangifera indica). So the specific epithet alone is not the species — you need the genus + epithet to name a species. NCERT calls the second word the 'specific epithet'.
This is a fixed universal rule of nomenclature. The generic name (genus) starts with a CAPITAL letter. The specific epithet starts with a SMALL letter. Example: Mangifera indica — capital M, small i. NEET frequently traps students by writing both with capitals (like 'Mangifera Indica'), which is wrong.
Mangifera is the generic name (the genus). indica is the specific epithet (the species part). Both words are italicised in print, or separately underlined when handwritten. The whole two-word name together is called the binomial name.
Yes. A genus can have many species, so many organisms can share the same generic name but have different specific epithets. For example, Panthera leo (lion) and Panthera tigris (tiger) share the generic name Panthera but differ in the specific epithet. The epithet is what separates closely related species inside one genus.
'X' and 'Y' are the components of Binomial nomenclature. This naming system was proposed by 'Z':
Which one of the following statements is not true about the universal rules of binomial nomenclature?
Try the real previous-year questions from this chapter — each with the answer and a full solution.
The generic name is the first word of a scientific name; it names the genus and starts with a capital letter (e.g., Mangifera).
The specific epithet is the second word of a scientific name; it names the species part and starts with a small letter (e.g., indica).
Carolus Linnaeus proposed binomial nomenclature, where each name has a generic name plus a specific epithet.
Both words are printed in italics, or separately underlined when handwritten. Capital first letter for the genus, small first letter for the epithet.
The Living World chapter is scoring and easy. NEET repeatedly tests which word comes first and the capital/small-letter rule (2016, 2019, 2023, 2026). Knowing generic vs specific epithet clearly gives you sure marks.
