3) Polyploids
4) Hybrids

Options

A. Somaclonal variations
B. Haploids
C. Polyploids
D. Hybrids

Answer

To solve the question regarding the use of colchicines in the production of specific types of organisms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Role of Colchicines**:
- Colchicines are chemical compounds that act as mutagens. They interfere with the normal process of cell division.

**Hint**: Remember that colchicines are not just any chemicals; they specifically affect cell division.

2. **Mechanism of Action**:
- Colchicines inhibit the formation of microtubules. Microtubules are essential for forming spindle fibers during cell division.

**Hint**: Think about what happens during cell division and the role of spindle fibers.

3. **Impact on Chromosome Number**:
- Normally, during anaphase of cell division, spindle fibers pull chromosomes apart, reducing the chromosome number by half. If colchicines prevent spindle fiber formation, the chromosomes are not separated properly.

**Hint**: Consider what would happen if chromosomes are not pulled apart during cell division.

4. **Resulting Condition**:
- Because the spindle fibers are not formed, the chromosome number does not get reduced. Instead, the cell ends up with multiple sets of chromosomes, a condition known as polyploidy.

**Hint**: Recall the definition of polyploidy and how it relates to chromosome numbers.

5. **Conclusion**:
- Therefore, the use of colchicines is primarily involved in the production of polyploids.

**Hint**: Focus on the final outcome of using colchicines in the context of chromosome number.

### Final Answer:
The use of colchicines is involved in the production of **Polyploids** (Option 3).
