I have big woolly sheep and wee baldy sheep, but I want BIG BALDY sheep! How can I get them?
X X Now we just need to breed from the big baldies to make a flock

How is it done? Genetic modification (GM) Changing the genes of a living thing, often by adding genes from another living thing.
This is a video of microinjection of a sheep pronucleus. The Sheep egg has been fertilized and is about to divide for the first time. The microinjection needle is delivering genetically modified DNA to the nucleus. If successful, this GM DNA will be incorporated into the nucleus DNA and will appear in every cell that divides afterwards, eventually resulting in a GM sheep.
GM can be used to combine genes from different organisms without breeding
What do you think? When is GM ok? If you cannot see the diamond nine image file on this page, you can find it on the Gene Jury website (GM diamond nine page).
