Artificial Selection DOK 2/3

How has artificial selection been used to influence the inheritance of desired traits in crops?

• By allowing crops to grow naturally without human intervention.

• By selectively breeding plants with desirable traits over several generations.

• By using random mutations to create new plant varieties.

• By cross-breeding plants with wild species to increase genetic diversity.

Analyze how artificial selection has changed the way humans influence the inheritance of traits in livestock. Use evidence to support your analysis.

• Artificial selection has no effect on livestock traits.

• Artificial selection allows for the development of livestock with traits that are beneficial for human use, such as increased milk production.

• Artificial selection leads to the extinction of livestock species.

• Artificial selection results in livestock that are less useful to humans.

What is a potential downside of artificial selection in agriculture?

• It leads to increased biodiversity in crops.

• It can result in crops that are more susceptible to diseases.

• It ensures all crops are resistant to pests.

• It has no impact on crop health.

Evaluate the ethical considerations of using artificial selection to modify organisms. What are the potential benefits and drawbacks?

• Artificial selection has no ethical considerations.

• Artificial selection can lead to ethical concerns about animal welfare and genetic diversity, but it also provides benefits like improved food production.

• Artificial selection is unethical and should be banned.

• Artificial selection only has positive effects and no drawbacks.

How does artificial selection differ from natural selection?

• Artificial selection is a natural process, while natural selection is controlled by humans.

• Artificial selection is controlled by humans to enhance specific traits, while natural selection occurs naturally based on environmental pressures.

• Both artificial and natural selection are controlled by humans.

• There is no difference between artificial and natural selection.

• Artificial selection has no long-term effects on the environment.

• Artificial selection can lead to reduced biodiversity and increased vulnerability to environmental changes.

• Artificial selection always improves environmental conditions.

• Artificial selection has only positive long-term effects.
