Genetics- Incomplete and Codominance

Front

What is Incomplete Dominance?

Back

A genetic situation in which neither allele is dominant, resulting in a blended phenotype in heterozygous offspring.

Front

What is Codominance?

Back

A genetic situation where both alleles are expressed equally in a heterozygous individual, resulting in both traits being visible.

Front

Give an example of Incomplete Dominance.

Back

An example is the flower color in snapdragons, where red and white flowers produce pink offspring.

Front

Give an example of Codominance.

Back

An example is the AB blood type in humans, where both A and B alleles are expressed.

Front

What happens in a heterozygous individual with Incomplete Dominance?

Back

The phenotype is a blend of both parental traits.

Front

What happens in a heterozygous individual with Codominance?

Back

Both parental traits are fully expressed and visible.

Front

How can you identify Incomplete Dominance in a genetic cross?

Back

Look for a phenotype that is a mix of the two parental traits.

Front

How can you identify Codominance in a genetic cross?

Back

Look for a phenotype that shows both traits distinctly without blending.

Front

What is the difference between Incomplete Dominance and Codominance?

Back

Incomplete Dominance results in a blended phenotype, while Codominance results in both traits being expressed.

Front

What is a phenotype?

Back

The observable physical or biochemical characteristics of an organism, determined by its genotype.
