If a diploid cell is treated with colchicine then it becomes
Correct answer: B. Tetraploid
- A. Triploid
- B. Tetraploid
- C. Diploid
- D. Monoploid.
Explanation
Colchicine is an alkaloid extracted from the seed and corm of Colchicum autumnale. It has the property of arresting and breaking the spindle so that cell division without cell wall formation may be affected leading to doubling of chromosome number. So a diploid cell will become tetraploid by chromosome doubling.
