identical twins do not have the same DNA, nor would you and your clone. present in all organisms is a certain amount of genetic drift that causes some to be different than others. Genes also change throughout the course of your lifetime. Hence the differences, non-environmental, that can be seen in "identical twins." In addition, cloning as we know it today would not produce someone who looked exactly like you, in fact it is far more likely that they would be decidedly different in many ways than it is they would be very much like you in the those same ways.
