• Are dominant traits more common than recessive
  traits?

Hypothesis If we survey many people for dominant
and recessive traits, then the (dominant or
recessive) traits will be more common.

SURVEY
1. Use the charts on lab book pages THAT I TOLD
YOU IN CLASS (THE HOMEWORK PAGES) to survey at
least five people.
2. They need to be family members. If you dont
have enough family members then do a friend but
it cannot be someone on the team.
3. Ask each person if they have the dominant or
recessive phenotype (physical characteristic) for
each trait listed.
4. Under the survey count the total number of
dominant and recessive traits.
5. We will fill in the Class Total part together
when everyone has completed their survey.
