Codominance vs incomplete dominance

Front

What is codominance?

Back

Codominance is a genetic scenario where both alleles in a heterozygous genotype are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive. Example: A calico cat shows both orange and black fur.

Front

What is incomplete dominance?

Back

Incomplete dominance is a genetic scenario where the phenotype of the heterozygote is intermediate between the phenotypes of the two homozygotes. Example: A black and white flower producing grey offspring.

Front

How does incomplete dominance differ from complete dominance?

Back

In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes, while in complete dominance, the dominant allele completely masks the effect of the recessive allele.

Front

What is a heterozygous genotype?

Back

A heterozygous genotype consists of two different alleles for a particular gene, one inherited from each parent.

Front

What is a homozygous genotype?

Back

A homozygous genotype consists of two identical alleles for a particular gene, either both dominant or both recessive.

Give an example of codominance in animals.

Back

An example of codominance in animals is the coat color of a calico cat, which displays both orange and black fur.

Front

Give an example of incomplete dominance in plants.

Back

An example of incomplete dominance in plants is when a red flower and a white flower produce pink flowers.

Front

What is the phenotype of a plant with incomplete dominance?

Back

The phenotype of a plant with incomplete dominance is a blend of the two parental phenotypes.

Front

What is the phenotype of a plant with codominance?

Back

The phenotype of a plant with codominance displays both parental traits distinctly, without blending.

Front

What type of inheritance pattern does a grey offspring from a black and white parent exhibit?

Back

The grey offspring exhibits incomplete dominance.
