Natural Selection

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

Natural Selection is driven by a change in the environment and survival of the

• Earth

• Fastest

• Fittest

• Biggest

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.

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice
• The hawks eat more dark mice than light mice because the dark mice taste better
• The hawks eat more light mice than dark mice because they can see the light mice more easily
• The hawks eat more dark mice than light mice because they can see the dark mice more easily

What process is being shown in this image?

• Variation
• Natural Selection
• Selective Breeding
• Homeostasis

"Organisms that are better adapted to the environment survive to pass traits to their offspring" is the definition of

• Natural Selection

• Evolution

• Selective Breeding

• Artificial Selection

According to natural selection, light colored tree trunks would favor

• light colored moths

• dark colored moths

• red colored moths

• red and light colored moths

What does the image represent?

• Founder effect
• Bottleneck effect
• Natural Selection
• Mutations

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 trait is an acquired phenotype.

Which of the following explains adaptation.

• An individual organism changes to meet its needs in the environment. These changes pass down to their offspring.
• The species as a whole changes their characteristics.
• Beneficial traits allow organism to survive and pass on those traits
• New characteristics arise in a species as needed.  If these traits are helpful, they are passed down.
