    What is a gene and where is it found?

4.

    Determine which allele you have of the following genetic traits: widow’s peak, free earlobe, dimples, curved Thumb, bent pinky, digit hair, rolling tongue, second toe longer.
    Using a punnet square, predict the ratio of offspring produced from these monohybrid crosses: TT (tall) crossed with tt (short), Tt (tall) crossed with Tt (tall), Tt (tall) crossed with tt (short)

5.

  1. What does the process of mitosis accomplish?
    Draw a sequence of cells that shows the process of mitosis including: prophase, metaphase, anaphase and telophase.
    Briefly explain how the DNA in the chromosomes is copied during this process.

    Do the cells resulting from meiosis remain haploid? Explain.

7. Describe how DNA encodes the specific proteins that result in genetic traits. Demonstrate your knowledge of this process by using diagrams or paper models.
8. What is a mutation? Using the diagrams or models created in question 7 to illustrate the effect of a mutation on the genetic trait.
9. Know at least five genetic disorders and tell a story about a famous person or someone that you know who has had one of these disorders.
