Before genetic engineering was developed, the improvement of crops involved hybridization, polyploidy, and mutation.

Question

Quizplus · Accepted Answer

Before the advent of genetic engineering, traditional methods such as hybridization (crossing different strains or species), polyploidy (increasing the number of sets of chromosomes), and induced mutation (using chemicals or radiation to create genetic changes) were used to improve crop characteristics like yield, disease resistance, and environmental adaptability.
