Mitosis is a process of cell division that results in two genetically {IDENTICAL} daughter cells. During mitosis, the genetic material is replicated, and each daughter cell receives an {IDRNTICAL} set of chromosomes. As a result, there is no introduction of new genetic variation. The genetic information is preserved, and mitosis is primarily responsible for growth, repair, and maintenance of tissues in multicellular organisms.
In contrast, meiosis (option D) is a type of cell division that leads to the formation of gametes (man-fluid and egg cells) and introduces genetic variation through processes like crossing over and random assortment of chromosomes.
Therefore, among the given options, mitosis is not a source of variation, as it maintains genetic identity in the resulting cells.
