incomplete and codominance

What is Incomplete Dominance?

Back

A genetic situation in which one allele does not completely dominate another allele, resulting in a new phenotype that is a blend of the two traits.

Front

What is Co-Dominance?

Back

A genetic situation where both alleles in a heterozygous individual are fully expressed, resulting in offspring with a phenotype that shows both traits distinctly.

Front

What is the phenotypic ratio when crossing a red flower (RR) with a speckled flower (RB) in codominance?

Back

2 red, 2 speckled.

Front

How does Incomplete Dominance differ from Mendelian inheritance?

Back

In Incomplete Dominance, the heterozygous genotype has a unique phenotype that is different from both homozygous phenotypes.

Front

What is an example of Co-Dominance in animals?

Back

A calico cat shows both orange and black fur, demonstrating co-dominance.

Front

What happens in a cross between two heterozygous individuals in Incomplete Dominance?

Back

The offspring will show a blend of the two parental phenotypes.

Front

What is the expected phenotype ratio in a typical Mendelian cross?

Back

The expected phenotype ratio is typically 3:1 for dominant to recessive traits.

Front

In a codominant cross, what would the offspring of a blue flower (BB) and a red flower (RR) look like?

Back

The offspring would be speckled flowers (RB), showing both colors.

Front

What is the significance of the heterozygous genotype in Incomplete Dominance?

Back

The heterozygous genotype expresses a phenotype that is intermediate between the two homozygous phenotypes.

Front

Can you give an example of Incomplete Dominance in plants?

Back

An example is the crossing of red and white snapdragon flowers, resulting in pink flowers.
