WebThe answer is C. Meiosis I and Meiosis II. The centromere separates during anaphase, allowing the sister chromatids to divide. The 46 freshly released chromatids can be dragged to one end of the cell, while the other 46 can be dragged to the other end as the kinetochore spindle fibers shrink. 12. WebMeiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II): Meiosis I 1. Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes. label for prowl h2o herbicide

"WebThe process of meiosis results in the production of four daughter cells, each of which has a set of two chromosomes after the process is complete. Cell division is regulated by checkpoints throughout the normal cell cycle, which examine the cell for any indications of damage or abnormalities in order to decide whether or not the cell will divide.
