Using this ability, Blake will be able to produce identical duplicates of himself and of any other person, as well as of any animal or plant. The clones will be able to think and act independently, and wouldn't be destroyed if the original died, but they will be indistinguishable from the original. However, the ability cannot be used on any non-living objects. It also cannot be used on a dead body, or on any materials derived from plants or animals.
