Codominance vs incomplete dominance

Front

What is Codominance?

Back

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.

Front

What is Incomplete Dominance?

Back

A genetic scenario where the phenotype of the heterozygote is intermediate between the phenotypes of the two homozygotes.

Front

How does Codominance differ from Complete Dominance?

Back

In Codominance, both alleles are expressed equally in the phenotype, while in Complete Dominance, one allele completely masks the effect of the other.

Front

What is an example of Codominance?

Back

The checkered pattern in chickens when a black chicken is crossed with a white chicken.

Front

What is an example of Incomplete Dominance?

Back

When red and white flowers are crossed, resulting in pink flowers.

Front

What is the phenotype of a heterozygous genotype in Incomplete Dominance?

Back

An intermediate phenotype that is a blend of the two homozygous phenotypes.

Front

What is the phenotype of a heterozygous genotype in Codominance?

Back

A phenotype that displays both traits simultaneously, such as a calico cat showing both orange and black fur.

Front

What type of inheritance pattern is shown when both traits are visible in the phenotype?

Back

Codominance.

Front

What type of inheritance pattern results in a mixture of traits?

Back

Incomplete Dominance.

Front

In a cross between a red flower and a white flower, the offspring are all pink. What type of inheritance is this?

Back

Incomplete Dominance.
