Autonym is valid in

Options

A. Only in botanical nomenclature
B. Only in zoological nomenclature
C. Both in botanical & zoological nomenclature
D. Only in bacteriological nomenclature

Answer

**Step-by-Step Solution:**

1. **Understanding Autonym**: An autonym is a specific term used in biological classification. It refers to a situation in trinomial nomenclature where the name of the species and its subspecies are the same.

2. **Trinomial Nomenclature**: This system involves three names instead of the two names used in binomial nomenclature. The three names consist of the genus name, the species name, and the subspecies name.

3. **Examples of Autonyms**:
- A classic example is "Homo sapiens sapiens," where "Homo" is the genus, "sapiens" is the species, and the subspecies is also "sapiens."
- Another example is "Panthera tigris tigris," where "Panthera" is the genus, "tigris" is the species, and the subspecies is also "tigris."

4. **Application in Nomenclature**: Autonyms are valid in both botanical (plant) and zoological (animal) nomenclature. This means that the concept applies to both plants and animals.

5. **Conclusion**: Therefore, autonyms are valid in trinomial nomenclature and can be found in both botanical and zoological classifications.
