Which one of the following character is common in classical taxonomy and modern taxonomic studies ?

Options

A. Morphological characters
B. Development process
C. Genetical characters
D. Ecological information of organisms

Answer

To solve the question regarding the common character in classical taxonomy and modern taxonomic studies, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Taxonomy**: Taxonomy is the science of classification of organisms. It involves grouping organisms based on shared characteristics.

2. **Identify the Types of Taxonomy**: There are two main types of taxonomy mentioned:
- **Classical Taxonomy**: This approach primarily relies on observable traits, particularly morphological characters (physical form and structure).
- **Modern Taxonomy**: This incorporates a broader range of criteria, including phylogenetic relationships, genetic information, and ecological data, but still retains morphological characters.

3. **Analyze the Options**: The question provides four options:
- A) Morphological characters
- B) Developmental process
- C) Genetical characters
- D) Ecological information of organism

4. **Compare the Options**:
- **Morphological characters**: Commonly used in both classical and modern taxonomy.
- **Developmental process**: More relevant in modern taxonomy but not a primary focus in classical taxonomy.
- **Genetical characters**: Primarily a feature of modern taxonomy.
- **Ecological information**: More relevant to modern taxonomy, not classical.

5. **Conclusion**: The only character that is common in both classical and modern taxonomy is **morphological characters**.

### Final Answer:
The correct answer is **A) Morphological characters**.
