Why exactly mitosis preserves a constant set of chromosomes in cells, and not in generations?

Because during mitosis, the number of chromosomes is doubled, thereby also the number of chromosomes remains in the daughter cells. During mitosis, the number of zromosomes at the end of the process is halved, which provides a diploid set of chromosomes characteristic of a given organism during the fusion of germ cells. In other words, 23 + 23 = 46 chromosomes in each person.
