30. If a diploid cell is treated with colchicine then it becomes
(a) triploid
(b) tetraploid
(c) diploid
(d) monoploid
Show Answer
Answer : b
Hints & Solutions
(b) Colchicine inhibits spindle formation, due to which chromatids are unable to separate during anaphase which results in doubling of chromosomes. So, if a diploid cell is treated with colchicine, there is doubling of chromosomes and it becomes tetraploid,. It is an alkaloid obtained from Colchicum autumnale.
