The correct terms are: Genotype refers to a person’s genetic makeup, while phenotype refers to a person’s physical characteristics.

Explanation

• Genotype is the complete set of genes or genetic material present in an organism, inherited from parents, which forms the blueprint influencing traits.

• Phenotype is the observable physical and biochemical characteristics of an individual resulting from the interaction of the genotype with the environment.

Thus, genotype is about the genetic instructions, and phenotype is the manifestation of those instructions in appearance and traits.
