The observable characteristics of an organism. These are determined by its genes (seegenotype), the dominance relationships between the alleles, and by the interaction of the genes with the environment. See alsonature and nurture.
Geology and Earth Sciences
Those observable properties of an organism that are produced by the genotype in conjunction with the environment. Organisms with the same overall genotype may have different phenotypes because of the effects of the environment and of gene interaction. Conversely, organisms may have the same phenotype but different genotypes.
Geography
The outward appearance, physical attributes, or behaviour of an organism, which develop through the interaction of nature and nurture. For phenotypic variation, see Robertson and Robertson (2008) J. Biogeog. 35, 5.
Philosophy
The gross physical and physiological features of an organism produced by the interaction of its genes and the environment. Contrasted with the genotype, which is an organism’s genetic constitution: this may include recessive genes, or those that are not expressed and have no effect on the phenotype. See alsoheritability.
