Which of the following processes does NOT result in genetic variation?

Mitosis is the process that does not result in genetic variation. It is a form of cell division that produces two genetically identical daughter cells from a single parent cell. During mitosis, the chromosomes are duplicated and then evenly distributed, ensuring that each daughter cell receives an exact copy of the parent cell's genetic material. This is crucial for growth, repair, and asexual reproduction, but it does not introduce new genetic combinations.

In contrast, meiosis, which is involved in the production of gametes (sperm and egg cells), introduces genetic variation through processes like crossing over and random assortment of chromosomes. Mutations, which are changes in the DNA sequence, can also create genetic diversity within a population. Therefore, while meiosis, mutation, and crossing over contribute to genetic variation, mitosis maintains the genetic status quo within cells.
