5.20 evaluate the potential for using cloned transgenic animals, for example to produce commercial quantities of human antibodies or organs for transplantation.

Advantages	Disadvantages
Animals that have beneficial products (e.g. cows with medicine in their milk can be cloned. Pigs with human hearts can be cloned for organ transplant). This means that the useful genetic characteristics  will always be passed on.	Some people believe that the cloned animals may not be as healthy as the normal ones
You can clone at anytime of the year – out of breeding season	Cloning is a new science. It may have consequences that we are not aware of.
You can clone infertile animals.	Difficult, time consuming and expensive.

5.16 understand that the term ‘transgenic’ means the transfer of genetic material from one species to a different species.
