Cloning

• Clone


  An individual produced asexually and genetically identical to the parent
• Cloning plants using cuttings

  1. Take cuttings from parent plant

  2. Stem is planted into soil

  3. Cover in clear plastic bag

  4. New roots develop

  5. New plant grows
• Cloning plants using tissue culture

  1. Use a mixture of plant hormones

  2. Produces a mass of identical plant cells called callus

  3. Use a different mixture of plant hormones to stimulate each cell to form a new plant
• Cloning animals using embryo transfer

  1. Give top quality cow fertility hormones so she can produce many eggs

  2. Eggs are fertilised by sperm

  3. Embryo is divided into several individual cells

  4. Each cell grows into an identical embryo

  5. Embryos are transferred to a host (surrogate mother) that has been given hormones to prepare for pregnancy

  6. Identical cloned calves are born but not biologically related to their mother host
• Cloning animals using adult cell cloning

  1. Take a cell from an adult

  2. Remove the nucleus from an unfertilized egg cell

  3. Insert the nucleus from the adult cell into the empty egg cell

  4. Use an electric shock to trigger the egg cell to start dividing and form an embryo

  5. Insert the embryo into the womb of an adult female
• The cells of your body constantly reproduce asexually to produce identical cells
• To take a cell from an adult and make an embryo is called adult cell cloning
