Transcript
QUESTION:
What the difference between dominant
and recessive genes?
ANSWER:
Dominant is always expressed when
present. Recessive is only expressed
when no dominant genes are present.
Students will be able to…
 Set-up and use a Punnett Square to
predict traits in offspring
 Compare dominant and recessive genes
and traits and observe them in humans.

Frequencies in the Classroom
QUESTION:
Are dominant traits more common then
recessive ones?
ANSWER:
Not always. A recessive trait can be more
common in some populations.
