Quizplus · Accepted Answer

Crossbreeding, genetic engineering, and polycultures of perennial crops are all methods used by farmers to increase crop yields. Crossbreeding involves breeding two different varieties of the same species to create a new variety that has desirable traits from both parent plants. Genetic engineering involves manipulating the DNA of a plant to introduce new traits or remove undesirable traits. Polycultures of perennial crops involve growing multiple crops together in the same field, which can increase overall productivity and reduce soil erosion.
