Answer:
(a) type 1 diabetes risk factors are likely more prevalent in caucasians than in other races
Explanation:
Both diabetes types, I and II, have different origins. However, they share the fact that people inherit only the predisposition of developing the disease and that the environmental conditions might trigger the expression of the disease. The final result is hyperglycemia and the risk of developing chronic microvascular and macrovascular complications.
In the case of Diabetes I, both parentals must provide the genes to the child. This is, the predisposition of getting the disease must be inherited from both parents.
It is suggested that white people express most commonly Diabetes 1, making it more common in caucasian people that show the highest rate of affection.
So to express diabetes 1, white people need to inherit the genes from both parents, but also they must be exposed to conditions that provoke the expression of diabetes. Environmentally, different factors might influence, such as weather, feeding habits, viruses, among others.
