Codominance and Incomplete dominance

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic scenario where one allele is not completely dominant over another, resulting in a blended phenotype in the heterozygote.

Front

Give an example of codominance.

Back

An example of codominance is a calico cat, which shows both orange and black fur due to the expression of both alleles.

Front

Give an example of incomplete dominance.

Back

An example of incomplete dominance is a red flower crossed with a white flower resulting in pink flowers.

Front

What is the phenotype of a heterozygous organism in codominance?

Back

In codominance, the phenotype of a heterozygous organism displays both traits simultaneously.

Front

What is the phenotype of a heterozygous organism in incomplete dominance?

Back

In incomplete dominance, the phenotype of a heterozygous organism is a blend of the two parental traits.

Front

How do codominance and incomplete dominance differ?

Back

Codominance results in both traits being fully expressed, while incomplete dominance results in a blend of the traits.

Front

What is the inheritance pattern of codominance?

Back

In codominance, neither allele is dominant, and both are expressed in the phenotype.

Front

What is the inheritance pattern of incomplete dominance?

Back

In incomplete dominance, one allele is not completely dominant over the other, leading to a mixed phenotype.

Front

What type of traits can exhibit codominance?

Back

Traits that can exhibit codominance include blood types in humans, such as AB blood type.
