Which term describes the observable characteristics of an individual?

• A. Allele
• B. Genotype
• C. Phenotype
• D. Homozygous

Answer: (C)

The term that describes the observable characteristics of an individual is phenotype. Phenotype refers to the physical expression of traits that can be seen or measured, such as height, hair color, and eye color. These characteristics arise from the interaction between an individual's genotype, which is the genetic makeup, and environmental factors.

To put it in a clearer context, while the genotype provides the specific genetic information that can influence certain traits, the phenotype is what actually manifests in the organism. This distinction is crucial in genetics, as it helps researchers and biologists understand how genetics can translate into visible traits.
