053 - Environmental Genotype Effects
Paul Andersen explains how genotypes can be expressed or not based on changes in the environment. He starts with a brief description of the Himalayan rabbit and how melanin production can be disrupted by high temperature. He explains how this could be advantageous in both the arctic fox and hare. He explains how flowers can vary temperature based on the pH of the soil. He finally describes gene expression in Lac+ bacteria.
