Genetic engineering is the process of breaking the natural boundaries that exist between species to produce new life forms that will produce a variety of desired traits. For example, genes from salmon can be spliced into tomatoes to make them more resistant to cold weather, thereby yielding a larger crop when the weather is less than favorable. Hybridization is the fertilization of the flower of one species by the pollen of another species-or artificial cross pollination (right?).
Many argue the two are essentially the same thing. "Here's the secret of hybrid corn. Hybridization is just crude genetic engineering," says the technology commentator Robert X. Cringley.
However many scientists, like the Cambridge-based Union of Concerned Scientists (
