Artificial Selection

What is the main difference between natural selection and artificial selection?

• Natural selection is controlled by humans, while artificial selection is not.

• Artificial selection occurs naturally, while natural selection is human-driven.

• Natural selection and artificial selection are the same processes.

• In natural selection, traits are chosen by the environment, while in artificial selection, traits are chosen by humans.

What is the role of a breeder in artificial selection?

• To randomly mate organisms without considering traits.

• To prevent any form of selection.

• To select and mate organisms with desirable traits.

• To allow natural processes to determine traits.

How did ranchers improve the jumping ability of horses?

• By training horses extensively from a young age.

• By mating male horses with jumping abilities with female horses with jumping abilities.

• By allowing horses to jump naturally without intervention.

• By feeding horses a special diet.

• Production of vegetables like broccoli, kale, and cabbage.

• Development of new fruit flavors.

• Increased resistance to animal diseases.

What did Gregor Mendel's research contribute to selective breeding?

The primary difference natural and artificial selection is

• In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).

• In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).

• Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.

• They are different terms for the same concept.
