For the cell, the job of meiosis is to reduce the number of gamete chromosomes from diploid to haploid. The job of meiosis in the chromosome is to go through both phases and produce more new cells to have the four haploid daughter cells. Finally, the job of meiosis in the organism is to reproduce sexually by producing sex cells in humans, animals, plants, and fungi. The differences between the stages of mitosis and meiosis are that in mitosis it has 1 cell division, duplicates DNA, occurs in somatic cells and no crossover occurs. In meiosis, it has 2 cell divisions, reduces DNA, occurs in gametes or sperm and oocytes, while crossing over occurs. They are both similar in that they create daughter cells, driven by at least one round of DNA replication, and have similar steps for cell division. The differences between the two phases of meiosis are that in meiosis I, as the cell undergoes the phases, prophase I, metaphase I, anaphase I and telophase I, it causes the cell to divide in two with each of the cells having a double stranded chromosome. But in meiosis II, it is just the division of the cells from meiosis I. The end result is four haploid daughters
