Twins are actual clones of each other. Artificial cloning would be like twins except with years or decades difference in ages.
As I understand it, that's a fairly accurate description of cloning.
However, as I also understand, science is now working on numerous DNA research projects that have identified various factors that make one susceptible to various diseases like cancer, sickle-cell, etc. If that research makes it possible to eliminate those diseases from the clone, wouldn't we want that option? Of course we would!
And therein lies one of the major issues with cloning. So, in effect, the laboratory would "creating" not an exact clone, but ...well, tweaked clone. And thus, we're stepping closer and closer to ...what... Frankenstein's monster, perhaps?
