alleryPolyploidy refers to:
AGain or loss of a single chromosome
BInversion of a chromosome segment
CIncrease in a whole set of chromosomes (often due to failure of cytokinesis after telophase)
DSubstitution of a single base in DNA
Answer & Solution
Correct answer: C. Increase in a whole set of chromosomes (often due to failure of cytokinesis after telophase)
**Polyploidy = increase in a *whole set* of chromosomes** (3n, 4n, etc.).
Common in plants (many cultivated crops are polyploid).
Arises from failure of cytokinesis after telophase of meiosis/mitosis.
