What does phenotype describe?

The term phenotype refers specifically to the observable physical characteristics or traits of an organism, resulting from the interaction between its genetic makeup (genotype) and the environment. In the context of animals, phenotype includes attributes such as size, color, shape, and other measurable traits that can be seen or assessed.

This understanding is essential in fields like animal breeding and genetics, as it helps specialists evaluate and select animals based on desirable traits. While options like genetic makeup, behavioral traits, and health status are significant aspects of an animal's overall composition and functioning, they do not directly pertain to phenotype. Phenotype is strictly related to the tangible, physical manifestation of genetics and environmental influences.
