We get a lot from our parents and heritage. I have my mother’s eyes as she had her mother’s eyes, I have my father to thank for being mechanically inclined. I could go on but you get the point. We receive so much from our parents and ancestors through DNA and learned behavior. Have you asked what if they passed down something that wasn’t beneficial? New studies are showing that PTSD can be passed not only through learned behavior, but through DNA.
