Multiple Choice

• the red allele making the fur red

• a new blended allele color of pink fur

• both alleles of read and white showing in the fur

Multiple Choice

Open Ended

How does the expression of traits in codominance and incomplete dominance challenge the traditional understanding of dominant and recessive alleles?

Multiple Choice

Which of the following best describes the difference between codominance and incomplete dominance?

• In codominance, both alleles are fully expressed, while in incomplete dominance, the phenotype is a blend of both alleles.

• In codominance, only the dominant allele is expressed, while in incomplete dominance, only the recessive allele is expressed.

• In codominance, alleles do not affect the phenotype, while in incomplete dominance, alleles are always expressed equally.

• In codominance, the phenotype is a blend, while in incomplete dominance, both alleles are fully expressed.
