Phenotypic Plasticity

Identical Twins - have the same genotype and might have similar phenotypes but not identical phenotypes due to the environment they developed in. The same genotype can still result in variation of phenotype based on environment.

Artic Foxes

The animal may have a thicker coat in the winter, but its underlying genetics have not changed. In this activity, students learn that arctic foxes have white coats in the winter and brown coats in the summer. This phenomenon is called phenotypic plasticity. The fox's genes do not change.
