Analyze the definition of each term

• Allele: An alternative form of a gene.
• Homozygous: Having two identical alleles for a particular gene.
• Phenotype: The observable physical or physiological traits of an organism, which are determined by its genetic makeup.
• Genotype: The genetic makeup, or set of alleles, of an organism.

Match the definition to the question

• The question asks for the term defined as "an organism's visible appearance."
• This directly matches the definition of Phenotype.
