Solution:
Two daughter cells have identical chromosomes if they are products of mitotic division. Therefore, if they do not have identical chromosomes, it is the product of a mitotic error.
Problems in mitosis can be in the germ cells or in the somatic cells.
Mitotic problems in the germ cells lead to numerical chromosomal alterations. In fact, In the complex process of cell division, things occasionally go wrong. A pair of homologous chromosomes may fail to separate during mitosis. This phenomenon is called nondisjunction. Conversely, homologous chromosomes may fail to remain together. These problems can result in the production of aneuploid cells. Aneuploidy is a condition in which one or more chromosomes are either lacking or present in excess.
On the other hand, mitotic problems in somatic cells lead to cancer.
Also, mitotic problems in the blastomeres lead to mosaicism. Mosaicism is when an organism has two or more cell populations that differ in its genetic makeup.
