All of the stages in the cycle are the same as in mitosis with the exception of metaphase 2 where instead of lining up in the middle the chromosomes line up in homologous pairs before being spread to the sides by the spindles. Mitosis produces daughter cells (diploid cells) that are identical to the. Then in mitosis it goes through the cycle once more and has interphase 2, prophase 2, metaphase 2, anaphase 2, and telophase 2. Mitosis only occurs in somatic (body) cells, while meiosis occurs in sex cells. Form 4 Science, Chapter 3.1 Compare and Contrast Mitosis and Meiosis. ![]() pptx), PDF File (.pdf), Text File (.txt) or view presentation slides online. On the other hand in Meiosis it goes through the five stages interphase 1, prophase 1, metaphase 1, anaphase 1, and telophase 1, and then goes through cytokinesis to divide the cytoplasm and create separate cells. 3.1 Compare and Contrast Mitosis and Meiosis - Free download as Powerpoint Presentation (.ppt /. Mitosis does each of these stages one time then has a stage called cytokinesis where the cytoplasm divides and the 2 cells are separated. Following interphase is prophase, metaphase, anaphase and telophase. The stages are interphase which includes the substages of G1, S, and G2. Mitosis and Meiosis have stages in their process that are almost exactly the same to one another with slight differences and amounts. Great as a homework assignment, review at the end of a unit, or an extra challenge for your GT kids. Those are the major differences between the process of Mitosis and the process of Meiosis. Test student understanding about the process of Mitosis and Meiosis using this Venn Diagram. ![]() Some DNA from the mother’s egg and some from the father’s sperm cell. Meiosis on the other hand has an end result of 4 haploid daughter cells that contain different genetic information from the parent cell. The end result of mitosis is 2 diploid cells that contain identical genetic information to the parent cell after its 4 stages. Mitosis, on the other hand, is focused on the growth and development of cells. Meiosis is required for genetic variation and continuity of all living organisms. They are two very different processes that have two different functions. After the chromosomes line up in the middle they are pulled apart by the spindles that were created in the prophase stage. The difference between Mitosis and Meiosis is quite apparent. In Meiosis it duplicates the 4 stages with only one difference which occurs in metaphase 2 where before the chromosomes line up in the middle of the cell they are lined up in homologous pairs on top of one another. Mitosis and Meiosis have the same first 4 stages, prophase, metaphase, anaphase, and telophase. The process of dividing for Mitosis has 4 stages while Meiosis has 8 stages. ![]() Meiosis is more complex and goes through. The way these cell division processes do this is by using chromosomes in the nuclei of the cells. In mitosis, the end product is two cells: the original parent cell and a new, genetically identical daughter cell. This results in an extra chromosome (n 1) in two of the gametes and a missing chromosome (n - 1) in two of the gametes.Both Mitosis and Meiosis have the goal to pass genetic information from one parent cells to multiple daughter cells. If nondisjunction occurs in meiosis I, the homologous pair of chromosomes remain bound. Nondisjunction may occur during meiosis I or meiosis II. \): Nondisjunction in Meiosis: Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during meiosis, resulting in an abnormal chromosome number.
