I think a great example of gene expression based on environment is that of the himalayan rabbit. Cold temperatures trigger black fur growth whereas warm temperatures allow the fur to be white.

Domestic cats are also good examples of two genetic phenomena:

Siamese cats can have white fur but dark paws and face, it's because of a temperature sensitive mutation enzyme.

Tortoiseshell cats are usually female, and the patterns in their fur are a result of X-chromosome inactivation happening in random clumps of cells.
