Objective:
 Analyze the inheritance patterns of Drosophila melanogaster (fruit fly)
Timeline
 Computer lab on Monday and Tuesday, assignment due Wednesday
Format
 Handwritten, electronic, or hardcopy
Notes
 Wild type flies are homozygous (pure)
Grading
 Assignment will be scored using the IB Criterion E Rubric for Processing Data
Assignment
Part I
1. Summarize the procedure beginning with purchasing flies to analyzing data.
2. What is the expected outcome if two wild type flies are mated? (ignore sex)
a. Sketch the Punnett Square
b. Summarize data
3. What is the expected outcome if a female wild type is mated with a male with white
eyes? (ignore sex)
a. Sketch Punnett Square
b. Summarize data
c. Which trait is dominant?
4. Use the offspring from #3 in a new mating. (ignore sex)
a. Sketch the Punnett Square
b. Summarize the data
c. Using the correct genetics vocabulary, describe the parents from this mating.
5. What are the results when a female wild type is mated with a male with dichaete
wing angle? (ignore sex)
a. Summarize the results
b. Sketch the Punnett Square
c. Which trait is dominant? Explain.
Part II
6. Develop a challenging testable question regarding the inheritance patterns of Drosophila
melanogaster (fruit fly) and use the simulation to conduct an investigation. Include the following:
a. Testable Question
b. Procedure (what flies are you going to mate?)
d. Results (percentages of each phenotype in the offspring)
e. Conclusion (use Punnett Squares to support conclusions)
Examples:



Follow a specific trait through multiple generations
Attempt to breed flies for specific traits
Evaluate all of the phenotypes of a specific trait and attempt to explain the inheritance patterns.
