Mitosis/meiosis question?

somatic cells have 2n chromosomes after mitosis. They are called diploid cells. Gametes, cells, have n chromosomes after meiosis. They are called haploid cells. Meiosis is cell division for cells. Mitosis is cell division for somatic cells( every other kind of cell). In Mitosis there is a preceding step called interphase. Interphase is broken up into 3 phases. First there is G1 phase. This is cell growth. Then there is S phase which is synthesis and replication of DNA. Lastly there is G2 phase which is where DNA errors are fixed. In G2 phase there is 4n chromosomes since the chromosome number had to be doubled so in cell division the daughter cells have 2n chromosomes. In Mitosis there is prophase where chromatin condenses into chromosomes and sister chromatids. Then in Metaphase the chromosomes line up along the metaphesal plate. Then in anaphase the sister chromatids are pulled apart to opposing sides of the cell. In telophase a cell membrane is created between both sides of the cell and then in cytokinesis occurs and the cell splits into two new somatic daughter cells.
