Individual plants or animals in a population with certain desired traits are chosen by breeders, farmers, or ranchers to mate. The people hope to get the desired traits in the offspring.

• Natural selection
• Selective breeding
• Gene flow
• Mutations

How can farmers best use selective breeding to increase apple production?

• By limiting the number of trees growing so they can have more space.

• By choosing trees that are the largest in size.

• By increasing the amount of water and fertilizer the trees receive.

• By choosing trees that consistently have the most apples.
