Do Now:

Take out your notes on Why is Meiosis important and How do Meiosis and Mitosis differ?

Lesson:

Desk Check

SLANT: Why is meiosis important?

  1. meiosis forms sex cells

    • haploid (half of the chromosomes)

  2. when two sex cells join this makes a diploid cell (zygote)

    • diploid cells are body cells and can grow into an organism

  3. big idea! Meiosis maintains diploid cells in sexually reproducing organism.

  4. big idea! Meiosis creates genetic variety in offspring.

    • each sex cell has a different half set of chromosomes from all others

    • Crossing over and random assortment of chromosomes make certain no to sex cells are exactly alike

    • Variety supports health and helps a species adapt when conditions change.

  5. both mitosis and meiosis start with diploid cells – but differ from there

    • meiosis undergoes one division and produces two diploid cells that are identical to the parent

    • this allows growth and repairing organisms

    • mitosis undergoes two divisions and produces four haploid cells that are different from each other

    • this make certain offspring all inherit different genetic information from each other creating variety
