Understanding Artificial Selection and Selective Breeding

What is the definition of artificial selection?

• The process by which organisms adapt to their environment naturally.

• The intentional breeding of organisms by humans to produce desired traits.

• The random mutation of genes in a population.

• The natural extinction of species over time.

What is one benefit of selective breeding?

• It increases genetic diversity.

• It can lead to the development of new species.

• It can enhance desirable traits in plants and animals.

• It eliminates the need for natural selection.

Which of the following is a risk associated with artificial selection?

• Increased biodiversity.

• Decreased genetic diversity.

• Natural adaptation to environments.

• Enhanced survival of the fittest.

Explain how artificial selection differs from natural selection.

• Artificial selection is a natural process, while natural selection is human-driven.

• Artificial selection is driven by human choice, while natural selection is driven by environmental pressures.

• Both processes are identical in their outcomes.

• Artificial selection occurs randomly, while natural selection is intentional.

Identify a scenario where selective breeding might be used to solve a problem.

• Breeding plants to survive in drought conditions.

• Allowing animals to breed freely in the wild.

• Introducing invasive species to new environments.

• Encouraging natural predators to control pest populations.

Discuss the potential impact of selective breeding on food production.

• It can decrease food production by reducing crop yields.

• It can increase food production by enhancing crop and livestock traits.

• It has no impact on food production.

• It can lead to the extinction of certain food species.

Analyze the ethical considerations of using artificial selection in agriculture.

• It is always ethically acceptable because it benefits humans.

• It raises ethical concerns about animal welfare and genetic manipulation.

• It is unethical because it mimics natural processes.

• It has no ethical implications.

Evaluate the long-term effects of reduced genetic diversity due to artificial selection.

• It can lead to increased resilience to diseases.

• It can result in vulnerability to diseases and environmental changes.

• It has no long-term effects.

• It ensures the survival of the species.

Predict how selective breeding might affect the future of biodiversity.

• It will increase biodiversity by creating new species.

• It will decrease biodiversity by reducing genetic variation.

• It will have no effect on biodiversity.

• It will stabilize biodiversity by maintaining current species.
