Answer: Meiosis
Step-by-step explanation:
Meiosis is a cell division that forms genetically different cells and reduces the number of chromosomes. This division only occurs with diploid cells → a 2n cell forms 4 distinct n cells, these cells are the gametes. Gametes are produced in gonads from a specific sequence of events called gametogenesis. Meiosis is always related to the reproduction of organisms.
Meiosis is important because it makes it possible to reduce the number of chromosomes in the cell (from 2n to n) so that, in case of sexual reproduction (fertilization), the diploidy of the species is maintained. And also because of the gene recombination that occurs through crossing-over, generating genetic variability.
