WebThe four aspects of Meiosis 2 are Prophase 2, Metaphase 2, Anaphase 2 and Telophase 2. The stages of meiosis 2 are as follows: Prophase 2: Here, we see the nucleoli and nuclear membrane disappear again. The chromatids get shorter and thicker. Chromosomes condense and centrosomes move to the opposite sides of the cell.
