      Hmmm this is an interesting question. But the answer is no. Because your DNA isn’t everything, it’s just instructions for how to make a body.

      It can make you more likely to act a certain way or talk a certain way, but ultimately it’s your environment that determines your behaviour.

      Think about identical twins, they have the same DNA and they look identical, and if they are raised in the same way they might talk and act the same, but probably won’t think exactly the same.

      If you take identical twins with the same DNA and separate them and raise them in different environments they will have totally different accents, personalities, habits, and might even look different (fatter, thinner etc)
