Answer:
An individual with an ll genotype (recessive) for the ear lobe shape trait will have a phenotype of attached ear lobes (option a).
Explanation:
The phenotypic expression of a recessive trait only occurs when both members of the allelic pair are recessive, while the presence of at least one dominant allele inhibits the expression of the recessive trait.
In this case, for the "ear lobe shape" trait, an individual with a genotype ll has a phenotype of attached ear lobes, which is recessive. In contrast, LL and Ll genotypes would express a free ear lobes phenotype.
