Your new favorite show has two identical twins who were separated at birth by the local town vampire who wanted to raise them as their own child. Twenty years later, they happen to run into each other at the mall and are shocked to see someone else looks just like they do! Although they share the same DNA and look the identical to each other, one twin has Type 2 diabetes, while the other does not. They are wondering if they truly are related! If you met them in real life, how could you explain to them that they are related, even though they are not following the same path related to their health? What might make them have different health issues?

Answer the following to get full points:

A: In conversational style, how would you explain to them that they are related even though one has Type 2 diabetes?

B: What causes one to have Type 2 diabetes and the other to not have the disease?

C: Answer in complete sentences.

A: You are definitely related — you look the same and you have essentially the same DNA because you are identical twins. That shared DNA means you inherited the same genetic blueprint, but genes are only one part of the story. How those genes are turned on and off, what you each ate, how active you were, how much stress you had, what you were exposed to before and after birth, and plain chance all change how your bodies work. So it makes perfect sense that two people with the same genes can end up with different health outcomes; having Type 2 diabetes does not change the fact that you are biologically siblings.

B: Type 2 diabetes is caused by a mix of genetic susceptibility and environmental or lifestyle factors that push the body toward insulin resistance and failure of the insulin-producing cells in the pancreas. Risk factors that can make one twin develop diabetes while the other does not include differences in weight and body fat distribution (especially visceral fat), diet, physical activity, sleep, stress, smoking, medications, and access to healthcare. Early life and prenatal factors and the twins’ gut microbiomes can also differ and affect metabolism. Epigenetic changes — chemical tags on DNA that alter gene activity without changing the DNA sequence — and random developmental or cellular differences can change how genes are expressed, so identical genomes can behave differently. All of these influences together determine whether someone with a genetic predisposition actually develops Type 2 diabetes.
