🧬 Part 1: Experiment Design

1. Choose your experimental approach:

Option A: Family trait data (eye color, tongue rolling, etc.)

Option B: Fruit fly trait observations (color, wing shape, eye spots)

2. Write your research question or hypothesis:

3. Identify your variables:

Independent variable (what you're testing): ________________________

Dependent variable (what you're measuring): ________________________

Control variables (what stays the same): ________________________

4. Outline your experimental procedure (list 3-4 steps):

📊 Part 2: Data Analysis & Genetics Concepts

5. Create a simple data table or chart in the space below to organize your findings:

6. Based on your data, which trait appears to be dominant and which is recessive? Explain your reasoning:

7. If a trait appears in 75% of offspring, what does this suggest about the parents' genetics?

Both parents are homozygous dominant

Both parents are heterozygous

One parent is homozygous recessive

Cannot determine from this information

8. Use probability to predict: If two heterozygous parents have children, what percentage would likely show the recessive trait? _______%

9. Summarize your experimental conclusions:

🎤 Part 3: Presentation Planning & Peer Feedback

10. Plan your 1-minute presentation. Check off what you'll include:

Clear statement of your hypothesis

Description of your experimental method

Data visualization (chart, graph, or table)

Explanation of dominant vs. recessive traits found

Scientific conclusions supported by evidence

11. After listening to other groups' presentations, provide feedback for one group:

Group presenting: _________________________

One thing they did well: _________________________

One question or suggestion: _________________________

12. Reflection: What was the most important thing you learned about genetic inheritance from this experiment?
