Population change handout
Use this handout while working through Allele Tracker and Gene Flow Mapper. Record what you
predicted, what you changed, what happened, and what evidence supports your explanation.
Part 1
Prediction
- Which force or condition are you changing first?
- What do you predict will happen?
- What result would count against your prediction?
Run notes
- What settings did you use?
- What changed across repeated runs?
- What stayed the same?
Part 2
Comparison
- How did the second run differ from the first?
- What evidence supports your explanation of the difference?
- What competing explanation did you consider?
Revision
- Did the evidence support your first idea?
- If not, what did you revise?
- What additional run would help test your current conclusion?
