Over the pass few week we have been doing a experiment/project of reproducing bugs, By mating with other classmates. So genetic variety had a big part in this because it gave us our geno types for our bug so we had to know what it looked like. If it was not for genetic variety then evry bug will be the sane it is like the same thing in us humans everybody if different and that is because we each have different genes that we get carried over from our parents so that would be the reason why you look like you family. a straight deffenition from wikipedia is A gene is the basic unit of heredity in a living organism. The gene comes from DNA which we all have in us so without genetic variety we would have no geno types and evry body would look and do the same.
