Mule is an example of

Options

A. interspecific hybridization , obtained by crossing male donkey and female horse
B. interspecific hybridization , obtained by crossing female donkey and male horse
C. out -crossing , obtained by crossing male donkey and female horse
D. cross breeding , obtained by crossing female donkey and male horse

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the classification of a mule. We need to determine what type of hybridization a mule represents based on the options provided.

2. **Identifying the Parent Species**: A mule is produced by crossing a male donkey (jack) and a female horse (mare). This information is crucial in identifying the type of hybridization.

3. **Defining Interspecific Hybridization**: Interspecific hybridization occurs when two different species are crossed. Since a mule is formed from a horse and a donkey, which are different species, this qualifies as interspecific hybridization.

4. **Evaluating the Options**:
- **Option A**: Interspecific hybridization by crossing a male donkey and a female horse. This is correct.
- **Option B**: Interspecific hybridization from a female donkey and a male horse. This is incorrect because it describes the reverse pairing.
- **Option C**: Outcrossing. This is incorrect as outcrossing refers to breeding within the same species but with unrelated individuals.
- **Option D**: Crossbreeding. This is also incorrect as it typically refers to breeding within the same species or closely related species.

5. **Conclusion**: The correct answer is Option A, which states that a mule is an example of interspecific hybridization by crossing a male donkey and a female horse.

**Final Answer**: Mule is an example of interspecific hybridization by crossing a male donkey and a female horse (Option A).
