Brief Discussion
Question: Think about a genetic disease caused by a single genetic defect. Will this genetic defect always present with the same phenotype or same clinical presentation in different individuals?
Answer: no.
Environmental Differences can effect the phenotype/clinical presentation in individuals. Environmental factors include diet, exercise, infectious agents, and altitude. Other genes and epigenetics may also influence phenotype.
