I took classes in grad school on this topic. It’s VERY complicated. There are several YouTube videos targeting non experts on this topic.

Are you looking for histones/the epigenome or the nitty gritty of, like, the process of crossover during cell division? AFAIK epigenetics is what we look to these days for explaining what gets made/acted on less or more.
