2.What phenotypes do you expect to see in the F1 generation of flies from this cross? Explain your answer.

3.Briefly describe the life cycle of the flies as it is happening in the tubes we are using. Where do you find the Drosophila at different stages?

4.Explain how the theoretical idea of ‘advanced’ and ‘primitive’ characters was applied to identify organisms in the Week 3 lab class. Give an example of how this worked.
