Answer:
A. I only
Step-by-step explanation:
An illustration of a phenotype might be.
An organism's observable traits, including as its physical attributes, behavior, and biochemistry, are referred to as its phenotype. These traits are produced as a result of how an organism's genotype interacts with its environment.
I. The creature has blue eyes. This is a phenotype since it describes an observable trait of the organism, such as eye color.
II. The organism has hemophilia, a genetic disease: This is not an illustration of a phenotype because it pertains to the genotype, or genetic make-up, of the organism. Hemophilia is a hereditary illness; it has no outwardly visible symptoms.
III. The organism is homozygous dominant (BB), which is not a phenotype because it pertains to the genotype, or genetic make-up, of the organism. The genetic composition of homozygous dominant (BB) is not an observable trait.
I, then, is the only suitable answer.
