While examining the mitotic stage in a tissue. One finds some cells with 16 chromosomes and some with 32 chromosomes. What possible reasons could you assign to this difference in chromosome number? Do you think that cells with 16 chromosomes number could have arisen from cells with 32 chromosomes or vice-versa?

This shows that the cells with 16 chromosomes are parent cells that had undergone mitotic divisions, whereas, cells with 32 chromosomes are the cells that had not undergone the process of segregation.
