Nature vs Nurture - AQA Biology

Why can some identical twins end up not identical at all? What is an identical twin? Are our characteristics predetermined by our genetics or can we influence them in other ways? These are all great questions and this video could go on forever without providing a completely concrete answer (not through any fault of my own!), but in this video we explore the Nature vs Nurture argument and discuss different scenarios in which genetics and the environment govern our fate.
