For example, when the body is infected with a disease, white blood cells of the immune system will express genes that produce antibodies. Injuries, such as cuts around wounds, will initiate the expression of genes in the cells of the injured tissues for clotting factors.

In certain species of alligators, eggs incubated at temperatures below 30°C will typically develop into females, while eggs incubated above 34°C will typically develop into males,
