In binomial nomenclature

Options

A. Both in genus and species the first letter is capital
B. Both genus and species are printed in italics
C. Genus is written in captial
D. Genus is written after the species

Answer

### Step-by-Step Solution:

1. **Understanding Binomial Nomenclature**: Binomial nomenclature is a system of naming organisms using two terms. It was developed by Carl Linnaeus, who is known as the father of taxonomy.

2. **Components of the Name**: The two parts of the name are:
- **Genus**: The first part of the name, which is always capitalized.
- **Species**: The second part of the name, which is always written in lowercase.

3. **Formatting the Name**: When writing the scientific name:
- Both the genus and species names should be italicized (or underlined if handwritten).
- There should be no space between the genus and species when written in italics.

4. **Example**: For instance, the scientific name for mango is *Mangifera indica*. Here:
- "Mangifera" is the genus and is capitalized.
- "indica" is the species and is in lowercase.
- The entire name should be italicized.

5. **Identifying the Correct Option**: When given options regarding the rules of binomial nomenclature:
- Look for the option that states that the genus name is capitalized, the species name is in lowercase, and both are italicized.

6. **Conclusion**: Based on the rules of binomial nomenclature, the correct format for naming organisms is to write the genus name first (capitalized), followed by the species name (lowercase), both italicized.
