Solution
The correct option is B Aneuploidy
Aneuploidy (heteroploidy) is a condition of having fewer or extra chromosomes than the normal genome number of the species. Aneuploidy commonly arises due to nondisjunction of the two chromosomes of homologous pair so that one gamete will have an extra chromosome (N + 1) while the other becomes deficient in one chromosome (N-1). Accordingly, the zygote thus formed will have additional chromosomes or will be a deficit in chromosomes.So, the correct answer is 'aneuploidy'.
