Difference between Telophase 1 and 2




  • Main Difference

    Different terms have the explanation that makes them different or like each other, but the main details that make them distinct are of utmost importance. This article helps to find the main differences between them. Telophase I become the first level of the process involved during the Meiosis 1 where the homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus to form two new cells. Telophase II becomes the fourth level of the process involved during the Meiosis II where the homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus and results in the formation of four daughter cells.

    Basis of Distinction Telophase 1 Telophase 2
    Definition Telophase I become the first level of the process involved during the Meiosis 1. Telophase II becomes the fourth level of the process involved during the Meiosis II.
    Working The homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus to form two new cells. The homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus and results in the formation of four daughter cells.
    Chromatin Formation The two daughter cells formed includes chromatid pairs along the cells attached to the tail of the nucleus. Chromatids do not exist along with the core in Telophase II.
    Spindle Spindle exists but disappears when the process completes. Does not exist.

    Telophase 1

    Telophase I become the first level of the process involved during the Meiosis 1 where the homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus, then the process of cytokinesis results in the formation of two new cells. The procedure may take a long time to complete, but that is because most of the processes take place at this stage and the rest of them complete at faster rates. The homologous chromosome moves towards the poles because of the action of the spindle and completes the migration processes. At this stage, each chromosome has two pairs of chromatids, and a new set of haploid exists at each pole. When this little process completes then the spindle disappears, and the envelope of nucleus gets formed around each set of the chromosome that become present at the poles. Now the process of cytokinesis begins, here the process becomes different for humans and animals. For the latter ones, a cleavage furrow gets formed due to the cytokinesis, and that makes the cell divided into two main types. When the process of cytokinesis completes, both these cells have a separate nucleus along with the chromosomes that have a haploid set. Most of the cells that are part of such a process do not go through the decomposition when the telophase 1 completes, while the ones who do show such a nature, the chromosome for them recondenses in the next phase that we know as prophase II.

    Telophase 2

    Telophase II becomes the fourth level of the process involved during the Meiosis II where the homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus, then the process of cytokinesis results in the formation of two daughter cells. These daughter cells have a haploid set of chromosomes around them. The process of this stage completes at a faster speed because most of the work that falls within the meiosis already complete in the previous.  The nucleus forms around the set of chromosomes and does so around each other, and this process provides the basis for new daughter cells. Then the process of cytokinesis begins which seems much different than the previous stage. As stated in the preceding paragraph, the homologous chromosome moves towards the poles because of the action of the spindle and complete the migration processes. Here, the process results in four daughter cells which are usually known as gametes for animal cells. These four cells have a haploid set of chromosomes for each other and therefore have the capacity of existing and mating with others. When the process of crossing over takes place some of the chromosomes mixes with the segments of previous versions and then from the first parental chromosomes, therefore, most infants have some of the same habits as their elders which may change such that it becomes less or more depending on the nature of the cells. Once this process completes the stage also end giving some maturity to the primary spermatocyte.

    Key Differences

    Telophase I become the first level of the process involved during the Meiosis 1 where the homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus to form two new cells.

    Telophase II becomes the fourth level of the process involved during the Meiosis II where the homologous chromosome pair reaches the poles of the cell and then get wrapped around the nucleus and results in the formation of two daughter cells.

    The procedure of Telophase I may take a long time to complete, but that is because most of the processes take place at this stage and the rest of them complete at faster rates. On the other hand, the process of Telophase II stage ends at a more rapid speed because most of the work that falls within the meiosis already complete in the previous.

    The two daughter cells formed during the Telophase I process includes chromatid pairs along the cells attached to the tail of the nucleus. On the other hand, chromatids do not exist along with the core in Telophase II.

    When this little process completes then the spindle disappears in Telophase I, on the other hand, it does not have any role in Telophase II.
