Metaphase II is when the sister chromatids line up along the metaphase plate. Prophase II is similar to prophase in mitosis, and no crossing over occurs during prophase II. Meiosis II consists of prophase II, metaphase II, anaphase II, and telophase II. Meiosis I results in two genetically different haploid cells after telophase I and cytokinesis which are similar to telophase and cytokinesis of mitosis. In anaphase I, the homologous pairs of chromosomes are separated and pulled to opposite sides of the cell leaving the paired chromatids still together (textbook, 97). Metaphase I is very similar to metaphase in mitosis because the homologous pairs of chromosomes line up along the metaphase plate. Crossing over is the very important reason that no two people have the same DNA. However, unlike prophase in mitosis, the two genetically identical sister chromatids pair off, and crossing over occurs between non sister chromatids. Prophase I, much like prophase in mitosis, is when the chromosomes shorten and the mitotic spindle forms. Meiosis I occurs first after DNA replication and consists of prophase I, metaphase I, anaphase I, and telophase I. Meiosis is broken up into into two parts: meiosis I and meiosis II which both consist of four parts. Meiosis, in contrast, occurs in gametes (sex cells), produces four genetically different daughter cells, and involves two divisions of genetic material. The division of the cytoplasm after nuclear division is called cytokinesis (textbook, 95). During telophase, the last stage of mitosis, the identical sets of chromosomes are at opposite poles of the cell, the chromosomes revert back to chromatin, and a nuclear envelope reforms around each group of chromatin. During anaphase, the chromatid pairs separate, and each half of the pair is called a chromosome.

During metaphase, the chromosomes line up along the middle of the cell, known as the metaphase plate.

During prophase, the chromatin condense into chromosomes, and the mitotic spindle forms (textbook, 94). DNA replication happens during S phase which is before the mitotic phase. Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase. Mitosis happens to replace dead or damaged cells or during growth. Mitosis happens in somatic cells (cells that are not gametes), and it produces two genetically identical daughter cells. Mitosis and meiosis are both forms of cell division, however, their processes are not identical.
