WebMar 2, 2016 · Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells. WebThe process of meiosis results in the production of four daughter cells, each of which has a set of two chromosomes after the process is complete. Cell division is regulated by checkpoints throughout the normal cell cycle, which examine the cell for any indications of damage or abnormalities in order to decide whether or not the cell will divide.
