Two organisms with the same genotype (e.g., identical twins) may have different phenotypes (e.g., one may be taller or heavier) if raised in different environments; those differences represent phenotypic plasticity.

WebThe observation that genetically identical organisms often vary greatly in phenotype clearly shows that gene-environment interaction is indeed an important regulator of phenotypic variation,... WebIn (a) stabilizing selection, an average phenotype is favored. In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed. In (c) diversifying selection, two or more extreme phenotypes are selected for, while the average phenotype is selected against. (Source: OpenStax Biology)
