Genes and the being of Gregor Johann Mendel are both crucial parts in the lives of everybody in the world today. If all the 6 billion people in the world had the same genes, imagine how boring life would be. We would all have the same freckles, we would all be of the same race, and we'd all be either boys or girls; so it would be impossible!!! The human race would disappear faster than ever! What would we do if Gregor Johann Mendel never existed? We wouldn't have nearly the same amount of knowledge on the human body that we have today. We're extremely ecstatic that we all have different genes and that Gregor Johann Mendel lived to show us that.
