WebApr 8, 2024 · Initially, taking as example a 2n somatic cell, ploidy increases to 4n (duplication of DNA) during interphase. During meiosis I, since homologous chromosomes are separated, ploidy falls to 2n (the original number) and then during meiosis II ploidy finally falls to n in the resulting daughter cells. Ploidy reduction does not occur in mitosis. WebBacterial binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes.
