Multiple Choice

What is natural selection?

• The process by which humans selectively breed plants and animals for desirable traits

• The process by which species adapt to their environment through random genetic mutations

• The process by which individuals with favorable traits are more likely to survive and reproduce

• The process by which humans modify the genetic makeup of organisms

Multiple Choice

Which of the following best describes a key component of natural selection?

• Genetic drift

• Competition for resources

• Environmental change

• Interaction between species

Multiple Choice

Which of the following is an example of natural selection?

• A bird with brighter feathers being more successful at attracting a mate

• A species of fish adapting to a warmer climate over several generations

• All of the above

Multiple Choice

Which of the following is an example of a trait that could be favored by natural selection?

• A plant that produces toxic chemicals to deter herbivores

• A mammal with a mutation that allows it to run faster than its peers

• All of the above

Multiple Choice

What is selective breeding?

• A process of natural selection in the wild

• A process of breeding animals and plants for desirable traits
