Paul [167]
In meiosis, cell division will occur two times. It shall be called Meiosis I and Meiosis II. And Meiosis happens to our sex cells, egg for female and sperm cells for the male. There four stages in Meiosis I, Prophase I will happen when who homologous chromosomes exchange DNA. Metaphase I will happen when the pair move together in the center. Anaphase I is when the who homologous chromosomes are pulled apart to opposite poles. Telophase I is when the the first division of the chromosomes happen. Producing two 24 chromosomes cells. The nest division will produce haploid or 12 chromosome cells. In Propase II, the nuclear walls will disappear once again, in the Metaphase II the cells will meet again in the center. In Anaphase II the chromatids will be pulled apart. And then lastly in the Telophase II, the chromatids will not be 2 haploids. So in Meiosis, 4 sex cells are produced.
