Final answer:
Commercial growers use grafting rather than seeds when they want to be sure the offspring are identical to the parent.
Step-by-step explanation:
Commercial growers use grafting rather than seeds when they want to be sure the offspring are identical to the parent. Grafting is an artificial method of asexual reproduction where a branch or bud from one plant is attached to a different plant, producing a novel organism called a chimera.
This technique allows growers to combine the favorable traits of two individuals into one, such as a good root system with a good shoot system.
