A cell divides by mitosis and gives rise to two daughter cells. Are these genetically same as the parent cell?

Answer 1

They are genetically identical to the parent cell.

When cells go through mitosis, they duplicate their DNA before actually dividing into two.

For this reason, the cells are genetically identical to the parent.

(Meiosis is another type of cell division, used only for production of gametes. In this type of cell division, the offspring generated are not genetically identical to the parent.)

Note that the parent cell splits into two new cells (which are the offspring) by mitosis. It does not produce two offspring in addition to itself. Two newly generated cells are genetically identical.

Yes, because the parent cell's chromosomes are replicated during mitosis and then equally divided between the two daughter cells, each daughter cell receives an identical set of genetic information to the parent cell, the daughter cells produced by mitosis are genetically identical to the parent cell.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
