The parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).

<h3>What genotype and phenotype?</h3>

The genotype refers to the information present in an individual's genome. Unlike the phenotype, it is not observable and rarely changes. The phenotype, in turn, depends on a combination between our genotype and the environment and can be defined as the observable characteristics of an individual.

With this information, we can conclude that the parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).
