Select the wrong statement about the rules of binomial nomenclature.

Options

A. Biological names are generally in italics and written in Latin
B. Generic name starts with capital letter
C. Both names are separately underlined when hand written to indicate their Latin origin
D. Author's name is never written after the scientific.

Answer

**Step-by-Step Solution:**

1. **Understanding Binomial Nomenclature:**
- Binomial nomenclature is a system for naming organisms using two names: the genus name and the species name.

2. **Analyzing the Statements:**
- We need to evaluate each of the given statements regarding the rules of binomial nomenclature to identify the incorrect one.

3. **Statement Evaluation:**
- **Statement A:** "Biological names are generally in italics and written in Latin."
- This statement is correct. Scientific names are indeed italicized and are typically derived from Latin.

- **Statement B:** "Generic name starts with a capital letter."
- This statement is also correct. The genus name (generic name) always starts with a capital letter.

- **Statement C:** "Both names are separately underlined when handwritten to indicate their Latin origin."
- This statement is correct as well. When handwritten, both the genus and species names are underlined to signify their Latin origin.

- **Statement D:** "Author's name is never written after the scientific name."
- This statement is incorrect. The author's name (usually abbreviated) is often included after the scientific name to credit the person who described the species.

4. **Conclusion:**
- The wrong statement about the rules of binomial nomenclature is **Statement D**.

**Final Answer:**
- The incorrect statement is: **"Author's name is never written after the scientific name."** (Option D)
