Hi Alex!

Great question! I'm actually not sure of the extent that the relationship between epigenetic and personality has been studied.

However, I did write some about epigenetic and its relationship to trauma (including inter-generational trauma). Experts have found that while we can't change our genetics, we can change our epigenetically transferred behaviors. So presumably I'd think epigenetic has some role in our personalities that we can change if we want. Here's the link if you're interested, but no pressure of course.
