Q:

How is meiosis II similar to mitosis?

A:

Quick Answer

According to McGraw-Hill, meiosis II and mitosis are similar because during both processes, sister chromosomes split along the center of the cell. During both meiosis II and mitosis, the sister cells line up down the middle of the cell and the spindle fibers pull them apart. The result is daughter cells that are genetically identical to one another.

Full Answer

Both meiosis II and mitosis have multiple phases. Meiosis repeats itself twice, which means that each phase occurs twice, once during meiosis I and again during meiosis II. The following phases are present in both meiosis and mitosis: prophase, metaphase, anaphase and telophase. During metaphase II of meiosis II and metaphase of mitosis, the sister chromatids align down the center of the cell. Anaphase and telophase of meiosis II and mitosis are similar as well. During anaphase, the chromatids separate. Then, during telophase, the nuclear membrane reappears, and the chromosomes uncoil. Next, the spindle apparatus breaks down, and, finally, the cell separates into two cells.

There is a difference between the cells in mitosis and meiosis II. During the first cell division of meiosis, the cells are diploid. When the second meiotic division occurs during meiosis II, it occurs as it does in mitosis. The cells double, but the number of chromosomes does not reduce.
