Environmental and Genetic Factors That Influence Health

Identify the environmental agent or genetic factor that you selected and the population health problem with which it is associated.
Evaluate the significance of the health risk resulting from your selected environmental agent or genetic factor, discussing such aspects as morbidity, mortality, incidence, prevalence, exposures, and costs to society. Support your response with references and data.
How might the environmental or genetic factor you identified result in health disparities in populations?
