Here’s What Smoker or Non Smoker Identical Twins Would Look like after Years of Smoking

When they are born, identical twins will have almost the same identical DNA but that doesn’t mean that their DNA profile will remain the same throughout their life. In fact, their DNA may change because of external influences such as lifestyle changes and choices, diets and habits like drinking or smoking.
