According to binomial nomenclature, which one is incorrect ?

Options

A. Tautonyms
B. Synonyms
C. Autonyms
D. Bionyms

Answer

### Step-by-Step Solution:

1. **Understanding Binomial Nomenclature**:
Binomial nomenclature is a system for naming organisms using two terms: the first term is the genus name, and the second term is the species epithet. This system was developed by Carolus Linnaeus.

2. **Identifying the Options**:
The options given in the question are:
- A) Tautonyms
- B) Synonyms
- C) Autonyms
- D) Bionyms

3. **Analyzing Each Option**:
- **Tautonyms**: These are names where the genus and species are the same (e.g., Gorilla gorilla). This does not fit the criteria of binomial nomenclature, which requires different names for genus and species.
- **Synonyms**: These are different names given to the same organism (e.g., Felis catus and Felis domesticus for domestic cats). Synonyms are valid within the context of binomial nomenclature.
- **Autonyms**: These are intraspecific names where the species epithet is repeated (e.g., Rubus subgenus Rubus). Autonyms are also valid in binomial nomenclature.
- **Bionyms**: This term is often used interchangeably with binomial nomenclature to refer to the two-part naming system.

4. **Conclusion**:
The incorrect term according to binomial nomenclature is **Tautonyms** (Option A), as it does not adhere to the requirement of having different names for genus and species.

### Final Answer:
The incorrect term according to binomial nomenclature is **Tautonyms** (Option A).
