Charateristic which delimit a family are more general than those which delimit a

Options

A. Cohort
B. Phylum
C. class
D. Genus

Answer

To solve the question "Characteristics which delimit a family are more general than those which delimit a...", we need to analyze the taxonomic hierarchy and the definitions of the given options.

### Step-by-Step Solution:

1. **Understand Taxonomic Hierarchy**:
- Taxonomy is the science of classification of organisms. The hierarchy includes several ranks: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
- Each rank groups organisms based on shared characteristics, with broader categories encompassing more general traits.

2. **Identify the Options**:
- The options provided are: Cohort, Phylum, Class, and Genus.

3. **Analyze Each Option**:
- **Cohort**: This term is not commonly used in biological taxonomy; it refers more to a group of individuals sharing a common characteristic in sociological studies. Thus, it is not relevant here.
- **Phylum**: This is a higher taxonomic rank than Family. Characteristics that define a Phylum are more general than those that define a Family.
- **Class**: This is also a higher taxonomic rank than Family. Similar to Phylum, Class characteristics are more general than Family characteristics.
- **Genus**: This is a lower taxonomic rank than Family. Characteristics that define a Genus are more specific and detailed compared to those that define a Family.

4. **Determine the Correct Answer**:
- Since the question asks for a rank that is more specific than Family, the only option that fits this criterion is **Genus**. Therefore, the correct answer is **Genus**.

5. **Conclusion**:
- The characteristics that delimit a Family are indeed more general than those that delimit a Genus.

### Final Answer:
The correct answer is **Genus**.
