OK, here we go...lol. There is a theory that we pick our parents before we are born. If genetic memory plays a part in reincarnation, do we also pick the same family genetics as our past parents as parents now to have that double whammy influence? Say we were once the child of Jack and Jill. Jack and Jill have also reincarnated and found each other in this life time (and did the same DNA search for their parents), so the genetics/DNA keeps running in this line. We then pick Jack and Jill to be our parents again and the DNA influence continues in the line.
I would do I graph of that but I suck at graphs.
Put another way, we have a bloodline running for Kings. Do we, as reincarnating souls, look for our "Kingly" bloodline to come back to?
