Web8 apr. 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. WebIt occurs only before Meiosis I. there is no interphase between Meiosis I and Meiosis II. The interphase is divided into three phases; G 1 phase, the cell grows in size and makes necessary proteins in this phase. S phase, the cell undergoes DNA replication. G 2 phase, the cell makes proteins that are needed for meiosis. http://cyberbridge.mcb.harvard.edu/mitosis_6.html in a bid to get the best and freshest
