Colchicine is a chemical used in botany to induce polyploidy because it inhibits:
Show answer and explanation
Correct answer: Spindle fiber (microtubule) formation
Colchicine binds to tubulin dimers, preventing their polymerization into microtubules. This stops mitosis before anaphase, resulting in a cell with double the chromosome number.
