Final answer:
The term 'phenotype' refers to all the observable traits of an organism, including physical characteristics and behavior which is the result of genetic expression and environmental influences.
Step-by-step explanation:
The observable appearance, behavior, and products of behavior of an organism is called its phenotype. This term encompasses all the observable traits expressed by an organism, including physical characteristics like color and structural morphology as well as behavior, which refers to how an organism acts in response to a stimulus. The study of animal behavior, known as ethology, often considers this within the context of evolution and natural selection. Phenotypes result from the combination of an organism’s genetics and its environment influencing which genes are expressed at any given time.
For example, the phenotype of a pea plant includes its height, flower color, and the shape of its seeds. These are all traits that can be directly observed.
