Meiosis and Mitosis comparision

Meiosis and Mitosis comparision. 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.

Presentation Transcript

  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.

  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?

  7. 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:
