5.2.1 Cloning in Plants and Animals

(a) outline the differences between reproductive and nonreproductive cloning
Clones ­ genes, cells or whole organisms that carry identical genetic material because they are derived from the
same original DNA.

Reproductive cloning generates genetically identical organisms.
Nonreproductive…
