I swear I'm stating to experience increasing levels of the Mandela effect (might not be the proper explanation) over the last few years, because this is the first time I've ever heard of genes being a thing which could change. Granted, I'm not a biologist, but we have sayings like "good genes" or "it's in the genes", and I've heard countless medical explanations that things are passed down "in the genes". Aren't genes directly linked to one's dna, and not a thing that any physical trauma or stress can physically modify? Why does this seem like it directly clashes with my life long understanding of "genes"? I'm possibly going insane, because odd things like this keep popping up and are a bit troubling in some odd dejavu kind of way
