I cant remember the book or if it was just a short story i read once anyway was an interesting read((sounds it hay)). The concept of the book was where humans where cloned at birth. The none clone when home with the parents and lived a normal life, the clone when to livein a controlled committee. One day the none clone gets ran over and need a new heart so they go get the clone kill it and harvest the organ. The writer goes on to evaluate what is a life and how can you apply a value to one and not the other with the same genetic code, how can you say that childe A is a clone and child B is not and in so decide if Child A or child B is going to be kept alive for organ harvest as and when the other needs one.

A interesting idea that I hope stays always an idea because that would suck being told hay your a clone one day we going to come alone and nick your organs for the other version of you that we decide is not a clone.

So here is a question if you have two cats both with identical DNA codes and age in a room with no other way of telling than looks and there DNA how do you tell the clone from the original or are they both clones of each other?
