Incomplete Dominance and Codominance

Front

What is incomplete dominance?

Back

A type of inheritance pattern where the traits of two alleles blend together in the offspring.

Front

What is codominance?

Back

An inheritance pattern where both alleles for a gene are fully expressed in the offspring.

Front

Give an example of incomplete dominance.

Back

When a red flower and a white flower produce pink flowers.

Front

Give an example of codominance.

Back

When a black chicken and a white chicken produce offspring with both black and white feathers.

Front

What percentage of offspring will be gray if incomplete dominance is present in a Punnett square with 50% gray offspring?

Back

50%.

Front

In incomplete dominance, what do the offspring look like?

Back

The offspring show a mixture of the traits from both parents.

Front

In codominance, how do the traits appear in the offspring?

Back

Both traits are visible and distinct in the offspring.

Front

What is a Punnett square used for?

Back

To predict the genetic outcomes of a cross between two organisms.

Front

What is the main difference between incomplete dominance and codominance?

Back

Incomplete dominance results in a blend of traits, while codominance shows both traits distinctly.

Front

What type of inheritance pattern is shown when yellow and blue flowers produce green flowers?

Back

Incomplete dominance.
