GENETICALLY MODIFIED PLANTS are now widely available to consumers, as discussed in chapter 6, and, as we have also seen, generate a significant amount of controversy. Yet genetically modifying plants may seem to many people to be much less controversial than tampering with the genetic blueprint of animals. This is due in part to our own view of animals. Indeed, for most people it is easier to relate to a dog, a goat, or even a mouse than it is to relate to a banana or a corn plant. What's more, the genetic engineering of animals immediately brings to mind the prospect of genetically modifying human beings. In this chapter we will see how scientists have created genetically modified animals and how gene cloning is being explored to treat genetic diseases in humans.
