<u>Colony morphology on agar</u>is NOT a phenotypic test.
Examples of phenotypic tests are;
Antibody reaction
Antibiotic resistance profile
Gram staining
Explanation:
Colony morphology is the visible shape taken by a colony of microorganisms. Phenotype, on the other hand, is the external traits of an individual organism based on its genotype and environmental influence. Colony morphology is not determined by the genotype of the organisms hence can't be considered a phenotype trait.
