Incomplete Dominance Codominance

Front

What is codominance?

Back

A genetic condition where both alleles for a gene are fully expressed, resulting in offspring with a phenotype that shows both traits distinctly, such as a calico cat with orange and black fur.

Front

What is incomplete dominance?

Back

A genetic condition where the phenotype of heterozygotes is intermediate between the phenotypes of the two homozygotes, such as a medium-length coat in rabbits from long-haired and short-haired parents.

Front

What is the phenotypic ratio when crossing a red flower (F^RF^R) with a speckled flower (F^RF^B)?

Back

50% red, 50% speckled.

Front

What is the blending of two traits called?

Back

Incomplete dominance.

Front

What is an example of codominance in animals?

Back

A calico cat showing both orange and black fur.

Front

What is an example of incomplete dominance in plants?

Back

A flower that is pink from a red (F^RF^R) and white (F^WF^W) flower cross.

Front

What does it mean if a trait is expressed in a codominant manner?

Back

Both alleles contribute equally and visibly to the phenotype.

Front

How can you identify incomplete dominance in offspring?

Back

By observing a phenotype that is a blend of the two parental traits.

Front

What is the difference between codominance and incomplete dominance?

Back

In codominance, both traits are fully expressed, while in incomplete dominance, the traits blend to form a new phenotype.

Front

What type of dominance is shown when a long-haired rabbit and a short-haired rabbit produce medium-haired offspring?

Back

Incomplete dominance.
