Incomplete Dominance Codominance

Front

What is incomplete dominance?

Back

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

Front

What is codominance?

Back

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

Front

In a cross between a red flowered plant (RR) and a white flowered plant (WW) showing incomplete dominance, what color will the offspring be?

Back

The offspring will be pink (RW), as the traits blend.

Front

If a child has wavy hair from a curly-haired mother and a straight-haired father, what type of inheritance is this an example of?

Back

This is an example of incomplete dominance.

Front

What percentage of offspring will have red flowers when a red flowered plant (RR) is crossed with a white flowered plant (WW) under codominance?

Back

0% will have red flowers; all offspring will show both traits.

Front

What is the phenotype of a plant with genotype RW in incomplete dominance?

Back

The phenotype will be pink flowers.

Front

In codominance, if a black chicken (BB) is crossed with a white chicken (WW), what will the offspring look like?

Back

The offspring will have both black and white feathers (BW).

Front

What is the main difference between incomplete dominance and codominance?

Back

Incomplete dominance results in a blend of traits, while codominance results in both traits being expressed distinctly.

Front

If a red flower (RR) and a white flower (WW) are crossed and show codominance, what will the offspring's phenotype be?

Back

The offspring will have red and white flowers (RW).

Front

What type of inheritance pattern is shown when a person with AB blood type has a child with a person with O blood type?

Back

This shows codominance, as both A and B alleles are expressed.
