Jamal’s father and grandmother are both diabetic. Jamal shows no signs of diabetes.Which most likely explains why Jamal never suffers from diabetes even though he has the genes that can cause it?

Having genes that increase the risk of diabetes does not mean a person will necessarily develop it. Healthy lifestyle choices, such as eating well and being physically active, can reduce the risk, so “He makes healthy lifestyle choices” is the most likely explanation. Refrigerating food and living in a city with good air quality do not directly explain why he avoids diabetes.
