Explanation

A genotype is an organism’s allele combination, inherited from its parents. A phenotype is an observable trait or physical appearance, which can be shaped by both the genotype and environmental influences, including the organism’s experiences. Choice C describes these terms correctly; experiences may influence phenotype, not the allele combination itself.
