Fruit Flies and Genetics Research
- 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?
- Model Genetic Organisms:Why are fruit flies considered a model genetic organism? Would humans fit this description?
- 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.
- 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?
- 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.
- Competition Between Species
- Competition occurs when organisms compete for access to limiting resources. Can you think of resources that are not limiting?
- 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.
