Question

Mitosis results in producing two cells which are similar to each other. What would be the consequence if the following irregularities occur during mitosis?

Centromeres do not divide

Answer 1

If the division of centromeres does not take place, then one of the daughter cells will get a complete pair of chromosomes and another daughter cell will get none. This may result in trisomy. Trisomy is a type of an abnormal number of chromosomes, i.e. aneuploidy.
