As Ray said, at birth we are a mix of the stress blueprint of our parents, grandparents, and great-grandparents. It is up to us to do what we can to change this blueprint for the better. At the very least, the inheritance landscape is looking a lot more Lamarckian these days. The Human Genome project is all but decommissioned at this point.
Moms can transmit psychiatric trouble to kids: study | Cornell Chronicle
"...Individual symptoms, such as anxiety, avoidance and a heightened response to stress, can be transmitted from mother to child and even grandchildren by multiple nongenetic mechanisms, a new study by investigators at Weill Cornell Medicine and other institutions shows. The pre-clinical findings, published May 13 in Nature Communications, may lead to tools to predict if a child is at risk of developing behavioral problems later in life after exposure to stress signals in the womb."
"...Studies in humans have previously suggested mothers can pass down behavioral traits to their children and grandchildren in a nongenetic manner. Grandchildren may be affected because fetuses produce early precursors to sperm and oocytes as they develop in the womb. A well-documented example of this transmission is the increased vulnerability of adult children and grandchildren of Holocaust survivors to psychological stress."
