I don't understand that; are you meaning traits passed on in DNA? They pass to the living yes but the dead aren't still sentient and alive as a result of this
I don't know, some suggestion has been made that DNA carries a certain sentience. I suppose If I were to reverse engineer the whole thing ( and that would take some doing) I would arrive at the conclusion that life is living through you.
I know that the individuals came to the end of their span but a part of them remains in us on a cellular level, It's how we came ito being.So It's a given we have their cellular memories at least.. It's not such a great leap for me then to suggest that we may carry other kinds of memory other than cellular. Memories we can at times access.
