FAQ
Frequently Asked Questions
No. While physical traits are a major component, phenotype also includes biochemical, physiological, and behavioural characteristics that can be observed or measured.
Yes. While the genotype is fixed (barring mutation), the phenotype can change due to environmental factors, development, and ageing (e.g., tanning, muscle growth).
A specific observable characteristic that forms part of the phenotype, such as height, blood type, or enzyme activity.
Natural selection acts directly on the phenotype—the physical and functional traits that affect survival and reproduction. The associated genotypes are then indirectly selected for or against.
The observable physical or biochemical characteristics of an organism, resulting from the interaction of its genotype with the environment.
