🧬 Part 1: Experiment Planning

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 (What do you want to investigate?):

3. State your hypothesis (What do you predict will happen?):

4. Identify your variables:

Independent variable (what you're changing): _________________________

Dependent variable (what you're measuring): _________________________

Control variables (what stays the same): ____________________________

📊 Part 2: Data Analysis & Genetics Concepts

5. Which trait type typically appears more frequently in offspring?

Dominant traits

Recessive traits

Both appear equally

6. If both parents have brown eyes (dominant) but carry a recessive blue eye gene, what percentage of their children might have blue eyes?

0%

25%

50%

75%

7. List the step-by-step procedure for your experiment:

8. Create a simple data table to organize your results:

9. Based on your data, what patterns of inheritance did you observe?

10. How does your data support or contradict your original hypothesis?

11. What scientific evidence from your experiment explains how traits are passed from parents to offspring?

12. What questions do you still have about genetic inheritance that you could investigate next?
