genotype denotes the specific genetic constitution of an organism, comprising the set of alleles—variations of genes—inheritied from both parents. This genetic framework determines the potential traits of the organism.

phenotype represents the physical and functional manifestation of that code. Phenotypes include observable characteristics like eye color, height, body shape, or behavioral traits.
