What is the relationship between type 2 diabetes and genetic predisposition?

Type 2 diabetes is known to have a significant genetic component, which makes option B accurate. Research has shown that individuals with a family history of type 2 diabetes are at a considerably higher risk for developing the condition compared to those without such a history. This heritability indicates that multiple genes contribute to the risk, influencing insulin sensitivity, beta-cell function, and the regulation of glucose metabolism.

Additionally, the genetic predisposition for type 2 diabetes is indeed stronger when compared to type 1 diabetes. While type 1 diabetes is primarily an autoimmune condition with a less clear hereditary component related to specific genetic markers, type 2 diabetes involves multiple genes that interact with lifestyle factors, such as diet and physical activity, to increase the risk.

The implication of a genetic link is that individuals with certain genetic risk factors may be more likely to develop the disease when exposed to particular environmental triggers, such as obesity and sedentary lifestyles. This multifactorial nature emphasizes the role of genetics alongside environmental influences in the development of type 2 diabetes.
