The genes in our DNA are what decided what our phenotypes would be, or how we were going to look like. But I don’t think it is accurate to say DNA is responsible for our phenotypes, I believe everything that affects our DNA is what is responsible for our phenotype. Our DNA would be different if I had different parents or if environmental factors took place. Yes, once the DNA is set into place it cannot change (obviously). But before that moment so much can happen that the possibilities are endless. Having a father of a different race or perhaps they had different dominant gene would have created a person that is completely different to who I am today. And when it comes to environmental factors, research shows that it can affect our genes to the point where it can turn some on and off. And when I mean environmental factors I mean emotions that specifically the mother during her pregnancy.
