WebTo summarize, meiosis is a cellular process in which a diploid parent cell divides into four haploid daughter cells. One very important event in meiosis is crossing over, which occurs between prophase and metaphase I. Crossing over increases genetic variation. The haploid cells produced through meiosis are otherwise known as gametes.
