1. Meiosis and Mitosis comparision

2. Mitosis: If a cell wants to make a duplicate of itself, it first must copy its DNA (part of a chromosome). The copies then must be separated & sorted into two sides of the cell. The cell then splits in two. Part of each parent is carried to the two new cells. Results in cells such as internal organs, skin, bones, blood, etc.

3. Mitosis

5. Meiosis: it first must copy its DNA (part of a chromosome). Results in reproductive cells (sperm, eggs, etc). Part of each parent is carried to the four new cells. Meiosis has evolved to solve a problem. The problem is this: Genetic Diversity of organisms – that is, they combine their genes together (creating genetic diversity). Why would this be a problem?

6. Meiosis

8. This may you remember these terms: MITosis takes the cell and Makes It Two (diploid) Meiosis has to do with sex cells (gametes) From the cell’s point of view: – mITosis results in Identical Twins (diploid) – mEioSis results in Egg and Sperm (haploid) Clyde Freeman Herreid – Dept. of Biological Sciences: Buffalo State Univ. of New York

9. Mitosis: Meiosis: Each resulting cell still has chromosomes from mom & dad

10. Comparision

11. Create a table and put the differences and similarities of Mitosis and Meiosis in it: MitosisBothMeiosis 1) Produces diploid cells2) Produces haploid cells 1) Divide cells
