Have you ever wondered why our environment is integral to our growth? Our surroundings and experiences can essentially modify the way we express and present ourselves to the people around us. That’s just personality is it not? But what if I told you that these experiences can change our blueprints as a person, the all important DNA coursing through our body. What would happen if these changes were carried to future generations? This is the premise of epigenetics, the study of how our behaviors and environment can change the way our genes are expressed. Tune in to find different experiments and explanations to delve deep into this fascinating phenomenon! In this fifth and final episode, we will discuss a real-life example where prenatal stress, due to the Quebec Ice Storm, could have caused genetic variation in the mothers' offsprings.
