epigenetics

What surprises a lot of people is that epigenetics may play a bigger role in determining which traits/characteristics you exhibit than your actual genes do (particularly biochemical traits). Scientists now believe your own genetics – your own DNA – determines less than 10% of the expression of certain traits, while epigenetics influences the other 90%. And prevailing wisdom says it can take one to three generations to reverse alterations to your genetic code and return to its original genetic blueprint.
