Data could probably be obtained. For example, children born from parents who experienced concentration camp life, if given up for adoption at birth would have supposedly inherited that DNA without the environmental input from their parents' (stories and recollections). It's possible the horrors were implanted in DNA (somehow) which could should up on some test. You'd think that's how instincts are transferred?

Studies like these are conducted on other health topics such as obesity. For example, Identical twins separated at birth are shown to exhibit the obesity tendencies of the genetic parents regardless of the environment the grow up in.
