BIO QUESTIONS

Research Requirement:

1. Fruit Flies and Genetics Research: Imagine you are working in a genetics lab with the fruit fly Drosophila melanogaster, a model organism for genetics research. You want to determine whether a trait you have discovered in fruit flies is dominant or recessive. • Explain how you would design an experiment to answer this question. • Predict what types of outcomes are possible. Which would indicate that the trait is dominant? Which would indicate that it is recessive? 2. Model Genetic Organisms: Why are fruit flies considered a model genetic organism? Would humans fit this description? 3. Adaptations to a Changing Environment • Explain why it is necessary for organisms to have the ability to adapt. • Why is the current environment making it difficult for organisms to adapt? • Explain how organisms develop adaptations. 4. Artificial Selection • Explain how artificial selection is like natural selection. • Why are quail useful subjects for an experiment on selection? What other organisms share similar characteristics? 5. Species Interactions • Describe the form of species interaction that was observed between members of lion pride and between lions and hyenas. • Explain how this type of interaction may affect the population densities of the two species. 6. Competition Between Species • Competition occurs when organisms compete for access to limiting resources. Can you think of resources that are not limiting? 7. Selection of Traits • Do you think natural selection has shaped traits in these species that makes them better competitors? • If so, what types of traits might be involved? Explain your reasoning.
