What is Codominance?

Back

A genetic scenario where both alleles in a heterozygous individual 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 a heterozygous individual is intermediate between the phenotypes of the two homozygous parents.

If a red flowered plant (RR) breeds with a white flowered plant (WW) and the offspring are all pink (RW), what type of inheritance is this?

Back

Incomplete Dominance.

Front

In a case of Codominance, what would the phenotype of a heterozygous individual be?

Back

The phenotype would display characteristics of both alleles equally.

Front

What is an example of Codominance in animals?

Back

The AB blood type in humans, where both A and B alleles are expressed.

Front

What is an example of Incomplete Dominance in plants?

Back

When a red flower (RR) and a white flower (WW) produce pink flowers (RW).

Front

How can you identify Codominance in a genetic cross?

Back

Look for offspring that show both parental traits distinctly, such as a flower with both red and white patches.

Front

What is the phenotypic ratio of a monohybrid cross showing Incomplete Dominance?

Back

1:2:1 ratio of phenotypes.

Front

What is the genotypic ratio of a monohybrid cross showing Codominance?

Back

1:2:1 ratio of genotypes.

Front

What does it mean if a trait is said to be 'blended' in inheritance?

Back

It refers to Incomplete Dominance, where the traits mix to form a new phenotype.
