Which process results in two daughter cells each having the same number of chromosomes as the parent cell?

Mitosis

Explanation:

Mitosis is the simplest and quickest mode of cell division. In this process a parent cell divides in such a way that it produces two daughter cells which are exactly the same as that of parent cell. They even have the same amount of genetic material i.e the chromosome.

While in meiosis, the second form of cell division four daughter cells are formed from one parent cell with just the half number of chromosomes as that of the parent cell.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.
