Which of the following is an example of selective breeding?
A species of the strawberry plant with large leaves is pollinated by a bee. The pollen is from a strawberry plant of the same species, but the leaves are slightly smaller. The result is a plant with medium sized leaves.
Cow birds pick insects off cows. This is beneficial to both organisms. The cows get insects removed that can bite them and transmit disease. The cow birds get a meal.
Some corn plants have adapted to being more drought resistant due to their environment.
Strawberries that are heat tolerant are crossed with strawberries that last longer after they are picked. The result is a strawberry that can withstand higher growing temperatures and have a longer shelf life
