- Who is the “father” of modern genetics?
- Name 2 examples of biological traits?
- Hair color and eye color are examples of a person’s what?

Human Genetics Unit
- Do identical twins have to look exactly the same? Explain
- What factors play a role determining your phenotype?
- If a genetic disorder is found mostly in males, the disorder is most likely what kind?
- What does it mean for a person to be a carrier for a disorder?
- Explain why most sex-linked disorders occur in males? (Hint: Think what makes a male different than a woman)

- What scientists are credited with the shape of a DNA molecule?
- What is the shape of a DNA molecule?
- What message does mRNA carry?
- What is a clone?

Evolution Unit
- What is an adaptation?
- Give an example of how one animal could be adapted for an environment better than another.
- The hind legs of a whale and wings of an ostrich are known as what kind of structures?
- What happens to organisms that are well adapted to their environment?
- What is sexual selection? Give an example
- A population that has a wide range of phenotypes would also have a large amount of what?
- Draw a standard bell curve. Then draw what happens to this curve during stabilizing selection, directional selection, and disruptive selection.
- What happens when some organisms leave a population and migrate into another area and join another population?
- Explain what happens during geographic isolation of a population. Give an example of how this might occur.
- Darwin’s finches had different shaped beaks but Darwin hypothesized what about these finches?
- What is a homologous structure?
