Unit Biology 1: Section 11.6

Why are individuals of the same species different from each other? What new methods do we have for producing plants and animals with the characteristics we prefer?

Scientists can now add, remove or change genes to produce the plants and animals they want

• to interpret information about cloning techniques and genetic engineering techniques
• to make informed judgements about the economic, social and ethical issues concerning cloning and genetic engineering, including GM crops
• Modern cloning techniques include:
  • Tissue culture using small groups of cells from part of a plant
  • Embryo transplants splitting apart cells from a developing animal embryo before they become specialised, then transplanting the identical embryos into host mothers
  • Fusion cell and adult cell cloning.
