I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.

REY [17]

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.
