Question

Explain the difference between selective breeding and genetic engineering in the development of food crops with desirable traits.
small paragraph

Answer 1

Selective breeding develops desirable crop traits by crossing plants with preferred characteristics and repeatedly selecting the best offspring over many generations, working only with naturally compatible parents and relying on existing genetic variation. Genetic engineering (including modern genome editing like CRISPR) directly alters a plant’s DNA—by adding, removing, or changing specific genes—which can be done faster and with much greater precision and can introduce traits not present in the species’ gene pool. In short, selective breeding is slower and less precise but uses natural crosses, while genetic engineering enables targeted, rapid changes and novel trait introduction.
