From the observation of the above given diagram, the sister chromatids are not separated which results in the abnormal distribution of the chromosomes in the daughter nuclei (as can be seen in the gametes). This phenomenon is called non-disjunction.
So, the correct answer is option D.

Question 1
Statement A: For a particular character in an individual, each gamete gets only one allele.Statement B: Chromatids of a chromosome split (separate) and move towards opposite poles during anaphase of mitosis.
Question 4
Chromosomes in metaphase get arranged at the equatorial plate (see Fig. 1). When these cells are treated with colchicine, cell division is arrested and the cells never enter anaphase. If we were to compare a colchicine treated cell at metaphase and an untreated cell in the same phase, we notice that chromosomes are more dispersed and do not arrange themselves on the equatorial plate in the treated cells (see Fig 2.).Using this information, which of the following will be affected by colchicine?
