Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
Codominance is a form of dominance where alleles of a gene pair in heterozygous is completely expressed resulting to offsprings with a phenotype that is neither dominant or recessive. Incomplete dominance is a form of dominance in which one allele of a specific trait is not completely expressed over its paired allele resulting to a third phenotype in which the physical trait is a combination of the phenotypes of both alleles. Therefore, they are similar in that in both combine homozygous dominant and homozygous recessive. They are different in that in codominance shows both, heterozygous while incomplete dominance shows mixture or blend, new trait and heterozygous.
