Phenocopy

The butterfly genus Vanessa can change phenotype based on the local temperature.

The larvae of Drosophila melanogaster have been found to be particularly vulnerable to environmental factors which produce phenocopies of known mutations; these factors include temperature, shock, radiation, and various chemical compounds.

In fruit fly, Drosophila melanogaster, the normal body colour is brownish gray with black margins.

When raised in moderate temperatures, Himalayan rabbits are white in colour with black tail, nose, and ears, making them phenotypically distinguishable from genetically black rabbits.

[3] Reversible and/or cosmetic modifications such as the use of hair bleach are not considered to be phenocopy, as they are not inherent traits.
