According to the
article below, ‘epi’ comes from the Greek for ‘over, on top of’. Epigenetics is an additional layer of instructions that lies ‘on top of’ DNA, controlling how the genes are read and expressed. That may be why the word "above" was used in the video.
For a while, I had been wondering how the sin Adam committed, that led to it entering the world, could possibly pass down the generations, and how the mankind God originally created as good could become wicked. Now we have a possible answer with epigenetics. It is possible that Adam's choice of disobedience to God, opened his eyes in a way that could alter his epigenetic marks, which passed onto his offsprings. Nevertheless, we still can't deny that we are responsible for the sins we commit ourselves.
But each one is tempted when he is drawn away by his own desires and enticed. Then, when desire has conceived, it gives birth to sin; and sin, when it is full-grown, brings forth death. (James 1:14 NKJV)

It is a choice whether we allow a seed to grow.
