text: yr. 11 biology genetic engineering? what sorts of developments are expected in the future of medicine and agriculture in the way of genetic engineering? yr.11 response please. corrective genetic engineering may involve the correction of genetic defects resulting disease phenotypes.  this may involve using an engineered virus to insert the genetic element to replace the genetic defect.    in agriculture, it is feasible to introduce new genetic elements to species to make them more resistant to diseases.
