Initial concentration

The Initial concentration genes dictate how much of one chemical is in a creature's "bloodstream" at birth. These can include:
 * glycogen
 * glucose
 * boredom
 * ageing or life
 * antibodies

Common mutations in these genes are stillbirths caused by lack of glycogen, and 'infantile advancement' - where the ageing or life is at a level so that a norn is seemingly born as an adult.
