Fænotypen
Fænotypen, commonly referred to as the phenotype, denotes the observable traits of an organism. These traits include external appearance such as height or leaf shape, as well as internal characteristics like metabolism, physiological processes, and behavior. The phenotype results from the interaction between the organism’s genotype and its environment, and can change with age or developmental stage.
The relationship between genotype and phenotype is not one-to-one. Traits can be simple, controlled by a single
Historically, the term reflects the observable “appearance” of an organism and contrasts with the underlying genetic
Examples of phenotypes range from obvious traits like flower color and body size to more complex features
Modern research emphasizes genotype–phenotype mapping, recognizing the roles of epigenetics, gene–environment interactions, and plasticity. While genomics
