Clones
- What are Clones?
  - Clones are Genetically Identical organisms.
- nature makes clones...
  - by asexual reproduction
    - asexual reproduction means that there's only one parent, all of the parent's offspring are genetically identical.
      - so do plants (like strawberries and garlic)
      - bacteria reproduce asexually...
      - and a small number of animals can, too (like greenfly)
  - when the cells of an embryo split.
    - a single egg is fertilised by a sperm, but it splits into two. all twins are clones!
  - but science does too...
    - scientists can now make animals clones in labs- like dolly the sheep
      - the nucleus is removed
        a nucleus from an adult donor is inserted in its place.
        the egg is stimulated so that i starts to divide as a normal egg would.
        the embryo is genetically identical to the parent cell.
