(Biologie) Ensemble des caractères visibles d'un organisme vivant.
Characteristics of an organism resulting from interaction between genetic and environmental factors.
In genetics, visible traits, those actually displayed by an organism. The phenotype is not a direct reflection of the genotype because some alleles are masked by the presence of other, dominant alleles (see dominance). The phenotype is further modified by the effects of the environment (for example, poor nutrition stunts growth).
The constitution of an organism as determined by the interaction of its genetic constitution and the environment.
