Web7. Interphase II In some species, the daughter cells go through a period of time, called interphase II, before the second stage of meiosis begins. In other species, the daughter cells immediately begin meiosis II after cytokinesis. Unlike the first division, the daughter cells do not undergo chromosome replication before entering meiosis II. 8. WebChromosomes are not duplicated during interkinesis. The two cells produced in meiosis I go through the events of meiosis II in synchrony.
