1. Survey Your TRAITS

2. Question: Are dominant traits more common than recessive traits?
Hypothesis:
If we survey many people for dominant and recessive traits, then the traits (dominant or recessive) will be more common.

3. Pedigree Use the chart to survey at least 5 family members.
Ask each person which trait they have – either dominant or recessive phenotype (physical characteristic).
Count the total number of dominant and recessive traits.
Bring chart to class to discuss as a team project.
