Both the poles now have full chromosomes.The meiotic spindles attach to chromosomes.ĪNAPHASE 2 - The sister chromatids are now pulled to both poles by meiotic spindles. The chromosomes line up in a vertical line along the equator of the cell and meiotic spindles start to form. The membrane around the nucleus in each daughter cell dissolves away releasing the chromosomes. In each of the two daughter cells, the chromosomes condense again into visible X-shaped structures that can be easily seen under a microscope. There is a full set of the chromosome on each pole.Ĭytokinesis: Both poles form nuclei and membrane starts to form. The pair of chromosomes is then pulled apart by the meiotic spindle, which pulls one chromosome to one pole of the cell and the other chromosome to the opposite pole similar to Mitosis but here, sister chromatids stay together. The centrioles release meiotic spindles which attach to the centre of chromosome pairs.
The chromosome pairs line up in a vertical line along the equator. It is completed before the cell proceeds to either metaphase I or to the second meiotic division.Īt the end of Prophase I, the membrane around the nucleus in the cell dissolves away, releasing the chromosomes. The pairs of chromosomes may then exchange bits of DNA in a process called recombination or crossing over.īecause of the exchange of genetic information (crossing over), it is one of the longest phases of meiosis. The copied chromosomes condense into X-shaped structures that can be easily seen under a microscope. The DNA replicates to create two identical full sets of chromosomes. The cell starts to prepare for cell division. MEIOSIS - Unlike Mitosis, Meiosis has in total nine steps for cells to divide and produce daughter cells. CYTOKINESISĬytokinesis is not a part of the cell division process, but it marks the end of the cell cycle and is the process by which the daughter chromosomes separate into two new unique cells. Previous phases are repeated, only in reverse. During telophase, the daughter chromosomes attach to their respective ends of the parent cell. This is the last phase of the mitotic cell division.
