WebThe increase in cytosolic Ca 2+ following fertilization also signals the completion of meiosis (Figure 14.42). In eggs arrested at metaphase II, the metaphase to anaphase transition is triggered by a Ca 2+-dependent activation of the anaphase-promoting complex. The resultant inactivation of MPF leads to completion of the second meiotic division WebThe difference is that in Metaphase-1 of meiosis the chromosome put together in two pairwise and therefore cross over takes place at the same time as in mitosis the chromosome organize in particular pair and no cross over takes place. In metaphase 1 the pairs of chromosomes referred to as bivalents are totally condensed. rock n roll high school trailer
