The promised leaner, faster-growing pig produced by genetic engineering is still under development. While the pig of the future may yield better meat and larger profits, hogs are now being produced for reasons other than pork chops and barbeque. Some day hogs may save lives and prevent blindness among other uses. The genetic engineering of pigs is being closely watched by doctors as these hogs are produced and studied. Genetic Engineering Genes control what a pig looks like and how fast it grows.
Pigs are different because they have different genes.
Here, genetic engineering means that we try to add an extra gene to the pig. While the purpose may differ, the basic idea is that the extra gene will have some effect on the pig such as faster growth or leaner growth. Genetic engineering is not really complicated, but it is somewhat difficult to accomplish. First, we must isolate a gene from the thousands of other genes in the pig. The gene we isolate is usually well-known and important to us.
