Multiple Select

Which of the following are characteristics of artificial selection?

• Man-made selection to breed desirable traits

• Requires human intervention

• Also known as selective breeding

• Occurs naturally without human help

Multiple Choice

What is the main purpose of selective breeding in agriculture and animal husbandry?

• To produce organisms with desirable genetic traits

• To allow random mating among organisms

• To increase the number of wild species

• To prevent domestication of animals

Multiple Choice

What are some reasons for creating new breeds and new varieties of plants or animals?

• To make animals smaller and gentler, and plants tastier and more drought resistant

• To increase the number of wild species

• To eliminate all genetic mutations

• To reduce biodiversity

Multiple Choice

Which of the following are possible negative consequences of selective breeding?

• Loss of speciation and poor adaptation

• Increased biodiversity

• Complete control over genetic mutations

• Guaranteed health of all animals
