Genetics Basics: Difference between Codominance and Incomplete Dominance

What did Gregor Mendel observe in his pea plant experiments regarding traits?

• Traits always blended together.

• Both traits appeared equally.

• One trait would hide or mask the other.

• New, unexpected traits always emerged.

In incomplete dominance, what happens when two different traits are crossed?

• One trait completely disappears.

• Both traits appear separately.

• A new, blended trait appears.

• The offspring only shows the dominant trait.

If a red snapdragon flower is crossed with a white snapdragon flower, what color would the offspring likely be due to incomplete dominance?

• Red

• White

• Pink

• Red and white striped

Which of the following best describes codominance?

• One trait completely hides another.

• Traits blend together to form a new trait.

• Both traits appear fully and separately in the offspring.

• Traits are only expressed in certain environmental conditions.
