Text Solution

Verified by Experts

The correct Answer is:
C
Aneuploidy (heteroploidy) is a condition of having fewer or extra chromosomes than the normal genome number of the species. Aneuploidy commonly arises due to non-disjunction of the two chromosomes of homologous pair so that one gamete comes to have an extra chromosome `(N+1)` while the other becomes deficient in one chromosome `(N-1)`
