If we all had the same DNA that would mean we would all be the same, no differences <span />
Low blood pressure on the other hand can be to do with:
Exercise and how much you do of it because regular exercise keeps blood pressure low.
Eating as after you eat, blood pressure falls.<span><span>
Stress causes blood pressure to rise.
Body temperature and how high it is affects BP because if you're body temperature is high, your BP is usually low.
Hope that helps.
