WebJun 8, 2024 · mitosis: the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division meiosis: cell division of a diploid cell into four haploid cells, which develop to produce gametes Gametogenesis (Spermatogenesis and Oogenesis) WebMeiosis is the process by which replicated chromosomes undergo two nuclear divisions to produce four haploid cells, also called meiocytes (sperms and eggs). Diploid (2 n) organisms rely on meiosis to produce meiocytes, which have half the …
