Autopolyploidy can be induced artificailly by

Options

A. chloroform
B. colchicine
C. chloroquine
D. colchine

Answer

**Step-by-Step Solution:**

1. **Definition of Autopolyploidy**:
Autopolyploidy refers to the condition where an organism has more than two sets of chromosomes, all derived from the same species. This condition can lead to increased size and vigor in plants.

2. **Induction of Autopolyploidy**:
Autopolyploidy can be induced artificially through the use of certain chemicals that affect the cell cycle and chromosome behavior during cell division.

3. **Chemicals Used for Induction**:
The primary chemical used to induce autopolyploidy is **Colchicine**. Colchicine disrupts the formation of the spindle fibers during mitosis, preventing chromosome separation and leading to the doubling of the chromosome number.

4. **Other Chemicals**:
While Colchicine is the most commonly used agent, other chemicals like **Chloroquine** and **Chloroform** may also have effects on cell division, but their use is less common in inducing autopolyploidy.

5. **Conclusion**:
To summarize, autopolyploidy can be induced artificially primarily by using **Colchicine**, along with other agents like **Chloroquine** and **Chloroform**.
