• 3 wrinkled: 1 smooth

• 2 wrinkled: 2 smooth

• none of these is correct

Fill in the Blank

Based on the baby elephant having smooth ears, the parents must be: (your answer should be: 1-heterozygous, 2-homozygous, or 3-both heterozygous and heterozygous

Multiple Choice

Which allele shows up in the codominant cross of the red and white cow in the previous slide?

• the white allele making the fur white

• 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

If red and yellow parent tulips are crossed and make orange F1 tulips, how do you correctly represent the parent genotypes?

• R=red, R'=yellow

• R=red, r= yellow

• C^R=red, C^Y=yellow

• none is correct

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.
