The ramps would carry over but by not utilizing them for a full life they would not be as high the next life. You wouldn't get the full benefit from them but depending on how advanced you were they could still be available in some form.
If you leave the family open and spark into a ward or another open family it's very possible someone could through their choices at character creation spark into your decendant. Your family will never leave the game and after a few generations they would be available for anyone to join. Now after you die and need a new body if there is a place open you could spark back into your original bloodline.
this game is going to be the death of both me and my wallet
