• 
• 
• 
• 

Which of the following best describes what the image represents?

• Natural Selection

• Artificial Selection

• Mutation

• Genetic Drift

Which of the following is an example of artificial selection?

• Gorillas are in the wild and have a baby gorilla.

• A group of ants in an ant pile are exterminated by an exterminator.

• A black speckled rabbit is a new favorite among children, a white and black rabbit are picked to make black and white baby bunnies.

• Wolves in the wild have pups.

White tigers are becoming extinct, to overcome this a male and female white tiger are paired together by humans to help their population continue to grow. This is an example of:

• Natural Selection

• Gene Flow

• Artificial Selection

• Genetic Drift

Blue catfish are going extinct. A dam in a lake full of blue catfish bursts due to poor engineering and kills some of the blue catfish. This is an example of:

• Natural Selection

• Gene Flow

• Mutation

• Genetic Drift

Green rhinocerous beetles are some of the biggest beetles to exist on Earth. A green rhinocerous beetle leaves its group and wonders over to another group that only has red rhinocerous beetles and mates with the red beetles. This is an example of:

• Gene Flow

• Genetic Drift

• Mutation

• Migration

A yellow morph and green morph of an insect lives in the rainforest canopy. You would expect:

• the green population to increase and the yellow to decrease

• both populations should stay the same

• both populations will increase

• the green population to decrease and the yellow to increaseThis is a wrong answer

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.

Mutations are a change in what?

• DNA

• tRNA

• protein

• rRNA

According to natural selection, light colored tree trunks would favor

• light colored moths

• dark colored moths

• red colored moths

• red and light colored moths
