          Transgenic animals.
          This unit can be used to consider some of the issues surrounding
          the uses and potential uses of transgenic animals. It starts
          with a brief outline of the techniques used to transfer genes
          in animals and then provides materials for classroom activities
          that consider some of the implications. Guidelines and background
          materials are provided for two role play debates, one considers
          the use of transgenic mice in medical research, and another the
          use of transgenic salmon for food. Finally there are classroom
          materials outlining the true story of Tracey, the first transgenic
          sheep to produce a life saving medicine in her milk.
