Codominance and Incomplete dominance

Front

What is codominance?

Back

A genetic condition where both alleles for a gene are fully expressed, resulting in offspring with a phenotype that displays both traits equally.

Front

What is incomplete dominance?

Back

A genetic condition where the phenotype of heterozygotes is intermediate between the phenotypes of the two homozygotes, resulting in a blending of traits.

Front

Example of codominance in plants?

Back

In flowers, a plant with one allele for red petals and one for white petals may produce flowers with both red and white patches.

Front

Example of incomplete dominance in plants?

Back

In snapdragons, crossing a red flower with a white flower results in pink flowers, showing a blend of the two colors.

Front

What is the phenotype of a plant with codominant alleles?

Back

The phenotype will show both traits distinctly, such as a flower with both red and white patches.

Front

What is the phenotype of a plant with incomplete dominance?

Back

The phenotype will be a mix or blend of the two traits, such as a pink flower from red and white parents.

Front

How do codominance and incomplete dominance differ?

Back

Codominance shows both traits distinctly, while incomplete dominance results in a blend of traits.

Front

What is an example of codominance in animals?

Back

In cattle, a cross between a red cow and a white cow can produce roan offspring with both red and white hairs.

Front

What is an example of incomplete dominance in animals?

Back

In certain breeds of chickens, crossing a black-feathered chicken with a white-feathered chicken can produce gray-feathered offspring.

Front

What is the role of alleles in codominance?

Back

Both alleles contribute equally to the phenotype, and neither is dominant over the other.
