Objectives. Define mitosis.. Define meiosis.. Analyze function of mitosis and meiosis in cell differentiation.. Mitosis:. If a cell wants to make a . ____________. . of itself, it first must copy its DNA (part of a chromosome).. Gamete vs. Zygote. What is a Gamete?. Egg & Sperm . What is a Zygote?. When two gametes come together (fertilization). Why your body can . not. use mitosis to make sperm or eggs?. A typical cell in your body has 46 chromosomes (23 pairs of homologous chromosomes). Suppose that human sperm and eggs were produced by mitosis. How many chromosomes would each sperm or egg have?. Cells Alive- . http://. cellsalive.com/meiosis.htm. .
