Examples:
Dominant and
Recessive Traits
What are your traits?
• We will look at some examples of human traits
that are determined by simple genetics.
• On your hand-out, record which phenotype
you exhibit.
• You may have to ask your partner to help you
determine a trait.

Data
• We will now record our class data and graph
our results
• Does our data support which genes are
dominant and which genes are recessive?
• What about the whole Purple Team?
