Crossing of individuals of two different to produce a hybrid is called

Options

A. Interspecific hybridisation
B. intervarietal hybridisation
C. intergeneric hybridisation
D. intravarietal hybridisation

Answer

To answer the question, "Crossing of individuals of two different species to produce a hybrid is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- We need to clarify what is meant by "individuals of two different." This refers to individuals that belong to different species.

2. **Identify the Type of Hybridization**:
- The question is specifically about hybridization, which is the process of crossing two different individuals to produce offspring.

3. **Differentiate Between Types of Hybridization**:
- **Interspecific Hybridization**: This involves crossing individuals from different species within the same genus. For example, a mule is produced by crossing a male donkey and a female horse.
- **Intervarietal Hybridization**: This involves crossing individuals of the same species but different varieties.
- **Intergenic Hybridization**: This refers to crossing individuals from different genera.
- **Intra-varietal Hybridization**: This involves crossing individuals of the same species and same variety.

4. **Select the Correct Answer**:
- Since the question specifies "two different," we focus on interspecific hybridization, as it involves crossing individuals from different species.

5. **Conclusion**:
- The correct answer to the question is **interspecific hybridization**.

### Final Answer:
The crossing of individuals of two different species to produce a hybrid is called **interspecific hybridization**.
